First the ARII kits. They were originally molded by Otaki, and it's already been said that their shining feature is exterior detailing, and that is so. Engraved panel lines and understated rivet detail were their hallmark, at a time when such did not exist elsewhere - we're talking late 1970's here. Only ESCI really had a handle on the notion of engraved, fine detail at that time, and that only in 1/72.
Interior details, wheel wells and the sundry fussy things we take for granted today, however, were sparse on the Otaki/ARII kits - which has also been mentioned. Your best bet is to either, a) see them as a blank canvas for super-detailing, or b) use whats there, keep the canopy closed and give them an exterior "Wow!" finish.
The places Ross has mentioned as sources are all good - Ive used all of them. I like Sprue Brothers and Roll Models. But to be honest, these are retail outlets, including my old pal Jeff Garrity at rare-plane detective. These people are not in business to give you a deal. So let me be one voice that endorses ebay. It can be an overall part of your hobby if you learn "the ebay buzz."
On ebay, three primary elements, the Ebay Trinity, must be in your mind:
- Watch pricing. Many people think ebay is a retail outlet, and try to price accordingly. You see them re-listing and re-listing all the time, too, because they misunderstand their customer base. Ebay is an auction site and should be treated as such. people come there to get a deal, not pay what they can pony up somewhere else. Some good deals can be had there - I just got the Minicraft 1/72 Ventura on ebay for $5. I got the Promodeller Me 410 for $11, there, not long ago. But, you have to be persistent, patient and willing to go past those sellers who think it is just another store front. Understand auction buying and find sellers who do, too, and it can be a good place.
- Watch shipping. Many sellers opt for the easy way out and hit you with max cost, flat rate shipping. This tactic alone hits the buyer in the wallet more than any other. Then they add little tiddly fees, like bubble wrap and tape and "handling charges." In essence, they see shipping as a profit vehicle.
I also do a lot of model trading and ebay selling myself, personally. I've done hundreds of transactions there. I know what it costs to ship an item. There is no way a model should cost $15, or more, to ship anywhere in the U.S.... but you see that all the time. Even more insulting is these same sellers try to foist these things off as part of their 'service.' That's bunk. Learn to use the USPS shipping calculator and when you find a seller that charges actual shipping based on where you live, stick with that person.
- Learn to use the "Completed listings" feature. This research tool lets you see what those items you are interested in actually sell for. For example, lets say you find long lists of similar listings that didn't sell. It's usually easy to figure out why. If you find those that have sold, then you immediately know what the market will bear for that item. Soon, a pattern will emerge, steering you to what are real world prices and thus, winning bids. Sellers only rarely use this tool, because, again, they have the wrong idea about ebay. That is to their disadvantage - there is no "magic wand" to savvy up clueless sellers. But it is there for you to take advantage of and help you steer clear of them.
Back to ARII kits. In the 80's they were the foundation for many super detailed builds and to this day they make a decent model if you accept their limits. Add a decent AM resin set to an ARII/Otaki/AMT** that was purchased fro a fair price and you have a great combination. But, if you're paying more than $10-15 to get one, its too much.
** Several of the more popular Otaki/Arii kits were also sold under the AMT label in the 90's. These include the Jap Zero, Me-109, Fw-190, Spitfire, P-51 Mustang, etc. The lesser known Japanese subjects were not included in these boxes. however, I'm convinced that these kits spurred the Asian giants (Tamiya and Hasegawa) into updating these subjects, items that were previously only seen in OTAKI/ARII boxes.
