i know there are forum members w/ some antipathy for this source, but i often see 1/32 Mosquitos on ebay for very reasonable prices. i got mine there for about $16 (+ shipping which was around $7).
of course, i just did a search there and there are none!
but if you check periodically, some will likely turn up.
the important thing to remember while looking at (and bidding on) kits there is: the one you are looking at is probably not the last one in the world. so if there are two fools acting like it is, let THEM fight over it and pay too much. there will be others. and if the seller has a low feedback number or a lot of negative feedback, let it go, there will be others.
i looked on www.greatmodels.com and see that there is still plenty of 1/32 resin bits for the Mossie, but no kits. and the $$ for some of those resin bits is stout!
we pays our money and we make our choices. :-)
if i see a source for a 1/32 Mossie or an auction come up, i will post back to this thread.
good luck,
