Leader, preferably the 735 as I like the looks/quality of that one more than the 720.
...brass knuckle i suppose, though that sloping top tube is fugly.
or anything IRO makes, I would personally check out the IRO's
oh, and I guess that alien bikes frame is like 350,
sparton frames, I think they are about 250, both the alien bikes and the sparton frames are lugged, though I wouldnt much suggest either.
I would say IRO, they have both steel and aluminum frames, though pre-ordering a leader 735 would be a decent option if you like fatty aluminum tubing.
