i grew up in Tonawanda and now live in North Chili (near Rochester). my favorite junkyards near you are:
Abeles on Chew Rd. right by Smokin' Joes in Sanborn - this one is on the indian reservation and has a lot of stuff. they're pretty reasonable with prices.
Skyway in Buffalo - really big lot kinda down by the old grain elevators. OK with prices depending on who's working.
M&M U pull it on William in Buffalo - this yard is smaller than the other 2 but prices are really cheap. also you have to pay $2 to get into the yard.
