Cadillac Repair: FuelInjectors, autohelp, auto parts store

Question
Car runs,but rough. Told $125 for each/plus labor for a around 1500 dollars repair. Was told can purchase all for around $250/$300. Been told 2 dufferent things by 2 different garages?  Can fuel injectors be bought other than 125 each? Car is a 90 Cad. Eldo. Tried to find parts on auto sites? On SS can't afford 1500 dollar repair job. Any suggestions?

Answer
You can purchase fuel injectors at most ANY auto parts store and install them yourself.

Owning a Cadillac is bvery expensive. I worked on them for over 25 yaers and NEVERowned one due to their unreliability and expensive parts. Thank goodness I could fix it myself. But still would never own one.
