Yahoo auctions: not a bad source for kits.
Was just clicking through Yahoo and went to the Auctions section.
I typed in "model kit" in the search bar and came up with 57 items, some of which were interesting.
I typed in "model" and got 322 items, but many were model this or that and not a kit, but there were kits in addition to what I saw under "model kit".
Not as much variety as Ebay here but not a bad idea to glance at it from time to time and see what's there.
Some things I thought were rare and interesting were figure kits for some members of the Beatles.
They also had a kit for the 4077 Mash which I think includes a few tents etc, but would have to see it again to confirm contents.
Have a good night everyone,
Dave
