Wooden decks have their fans because they look good when everything goes well. They also have their detractors at least on Model Warship. Some folk have problems with the adhesive in the short run and the long run. The decks are not always cut precisely to fit the plastic. And you will get arguments about whether or not they're colored correctly. The decks I've seen would be darker than what I'm looking for on Konig. As for price, I've asked about Pontos because they're new in the game (I think) and do have good prices. Not so with everyone: one new company will sell me a Konig deck for $60 - the model cost $50.
All genres attract good modelers, but the ship gurus are extraordinary craftsmen who think little of doing major surgery on a model to compensate for a slightly fat funnel. The scratch building that goes on is remarkable. But no matter how good one is, if you do a complex ship, put on all of the available PE, metal barrels and wooden decks (not to mention stuff like replacing masts with brass and then sanding them to get a taper) and you are looking at one big project. (Ship builders are also the primary market for complete resin models.) I wouldn't call it expensive. If you went all out on a kit like the Hasegawa Mikasa it would go nearly $200 for all of the goodies. But it would take up more time than three or four aircraft (unless you build bi-planes: ship guys have been known to build biplanes.). I'd guess that there are more "ship only" modelers than in other genres, although I know a lot of plane/armor guys that don't build ships ever. I like them all. Probably means I'll never get good at any of them. But it also means that I wouldn't want to spend three months on one project. I'm enjoying Konig greatly, but already have my next two projects planned. Anyway, if I can become a competent ship modeler I'll be very pleased. Very good would take a miracle. But that will probably mean that I won't ever get all of the latest and greatest gadgets helpful for contests or simply have the desire to create the absolutely best model possible and heck with the time involved. But I have the greatest respect for purists: for one thing, it's the hard-core that push model companies to produce the high quality kits available today.
