Wow! I must really be in the budget barn. I have 6 bikes, and only two were purchased new.

'93 Specialized Crossroads.....$199.00 ( add used Nordic Track trailer......$50.00 at a flea market)
'83 Schwinn Sidewinder.......$149.00

My used bikes are as follows:

'86 Cannondale Criterium $125.00 at a pawn shop in 2006
'85 Giant Rincon $25.00 at a flea market in 2001
'62 Schwinn Varsity $10.00 bought from a neighbor in 1966
'81 Torpado (all Campy) $50.00 at a flea market in 1989

If I ever had $350.00 to spend on a bike, I would be in heaven.......

Look for a good used bike. They are all over the place.
