Personally I've got my fingers crossed. Two of the kits I ordered I thought were eBay only. My experience with GreatModels has been mixed. They've gotten things to my house - slowly - and never filled an entire order. That said, their web site was very specific about things being in stock. There's another place that reminds me of them: Roll Models. (It's both a net and a com: some interesting modeling articles on their home page.) Huge selection, very decent prices, one of the slowest places online and miserable customer support. That doesn't bother me if things get there. I've been collecting CDs far longer than models and have a stash well over 1,000. About a third of them came from Berkshire Record Outlet which has stunning prices and selection for classical and jazz. And if delivery is inside a month, you've done something to please Olympus. Doesn't surprise me that Sprue is thriving. Scale Hobbyist will beat them for prices (outside of Sprue sales items), but Sprue has outstanding selection, is very fast and I've never had an item in the cart that was out of stock. No wonder I've got about 60 kits unbuilt. Can't miss out on bargains can we?
