I've got my half built klunker from a Schwinn Point Beach. I like that it has canti mounts and a derailleur hanger already. Plus it's aluminum and like a sub 4 pound frame also. Mine is like a cross between a vintage road like with Molteni colors and a nice chrome lugged Ross fork and the bullmoose bars. I just have to find some wheels and cranks. I could probably just pick up a old mountain bike and run a single up front and either 7 or 8 in the rear.
A really cool bike was the Merlin Newsboy from like 10-15 years ago. Titanium cantilever frame. Now that was sexy and you don't see many around at all.
Plus this did the Newsboy in a straight bar DX style frame also
