I have a few 1/48, 1/32, and 1/72 kits and aftermarket items up for auction on eBay this week.
Auctions: http://www.ebay.com/sch/m.html?_nkw=&_armrs=1&_ipg=&_from=&LH_Auction=1&_ssn=mec211&_sop=1
I also have tons of Buy-it-now/best offer items. I'm more than happy to offer actual-cost combine shipping in the US on the auction and BIN items, which can save you tons!

Thanks for looking, and feel free to contact me if you have any que
