Im not into bmx biking but ive made a few trinkets and bikes before. I would use ebay for parts that arent very complicated and special (example. seat). CAUTION: as a general rule i woulnt buy anything online without extensive reasearch. Make shure u know wat u r getting before u buy it. Next i would look if there are any local bike stores that sell used/refubised/new parts. It is best to try to buy parts at sores so you can look at them first. Bring your work in progress with so you know if ur parts fit. Next (this may seem odd) but there are stupid people out there thatt throw away stuff that might be extremly good parts. If u r in school, on garbage day on the way to the buss stop sook for old bikes or parts. if they are any good, stash them in a bush in a neiboors yard and pick em' up on ur way home. one good website that i have used that was mentioned above is danscot. its very reliable.
GOOD LUCK DUDE
HOPE UR BIKE IS A BEAST
