Throttle Body sources

[Jason Weir]

I am looking for a source for a GM throttle body used on the 2.5 4 cyl
for my new project, actually its the same one used in the Fieros,
Ludis???.  I don't want to get a junkyard unit and wondering if anyone
has a source cheaper than the dealer, a reman would be fine... That was
a fairly common motor and it would seem that someone is selling those
things rebuilt... 

Did GM use any other single injector TBIs on any motors smaller than the
2.5, that still had the standard TPS, and IAC in it...

thanks Jason
