Lol, I forgot the only link that I myself have bought models from there (not counting the 1/200 link):
Reviresco: www.tin-soldier.com/cgi-bin/ustorekeeper.pl They have a bunch of planes from both WW1 and 2 in 1/144 for a good price. I only own WW1 models from them myself but they are the same srie and the ones I own are very well made. US store, reccomended both for DOW and Wow .
The sortiment from WW2 is somewhat odd (P-36, P40, V-1, Oka Baka, He 163, several fiat planes, Gloster Gladiator, Heinkel 51, Henschel Hs 123, A5M4, Ki-27, Ki-43II, ND 52, I-15, I-16, R-5 and SB-2. Their WW1 sortiment is however first class.
Maybe not the perfect collection since they have focused somewhat on weirder planes, if you order from them you will probably have to buy some planes from another place too but they are cheap, good quality and delivers fast.
