I'm with Tim all the way!!! I have about 10 internet shops in my favorites who I search for the same kit, before I buy. The funny thing is, when I go for PE, Resin parts, or references for a kit I usually end up ordering from 3 different sources!!!! And some only do A/C or only Ships, or only Autos, or a combo of everything!!! My top three are:
www.squadron.com
www.greatmodels.com
www.megahobby.com
All 3 have done great business with me, and are usually within a dollar or two within each other.
