the leader is a good choice.. just throwing this out there. i read that the windsors are rebadged fujis.. the frames are identical. i have owned 2 windsors and a 2002 steel fuji track. they have great geomoetry and we just picked up a 61cm windsor for my friend bryce last night. im looking at it right now, for $250 used its a great value.
check out sparton frames on ebay. they are great lugged steal track frames. i believe they are built in mexico. for around $180 frame/fork and custom colors available. my friend got a brown one with a metal flake on special request. they are great guys and good quality frames. not drilled for brakes and real tight geomoetry.
but just keeping an eye on craigslist is the best. theres a khs on there today for 300.. you can't beat buying a used bike with upgrade parts for a good price.. hell you get those chips and dents the first month you own it....
