The first one could be great to an airbrush build group ( build whatever you want as long as it is airbrushed) but modelers should live close from the others as you can lose a little pressure with a 300 km airhose. The second one : what are you waiting to check such bargain; a little advise from an " ebay sniper" : search what you might be interested in, when found, put it into " items to follow" and DON'T bid until last minute; this last thing depends of your connection. I personally write my bid at 40 to 30 seconds to the end and I press Enter ( must be around 20 seconds ) and I got a number of good hits but to do this I have a 2048 K connection and this is not the less important part of the process. And the most important is : if you see a battle on an object several days before the end, specially with low rated bidders ( in terms of bid, not of feedback) get away from this mess as it has chances to finish at an higher price than new and that is not what you want, is it ?
P.S. 1$ over the higher bid seems short as you never know how many snipers are here. And your bid is more effective is it is not "round" : 1.68 is better than 1 (or 1.65 or 1.81 or...)
