I don't know if I read in to it wrong or not, but is your beater the '08 Accord? If so, to have the A/C go out on a car that is relatively young means a couple things:
(1) If the coolant is low / leaking, there is a massive leak. Not necessarily a high dollar fix, could simply be a hose that rubbed against something, replace the hose, have the system evacuated and charged (correctly), might be a couple hundred bucks.
(2) A mechanical / electrical component has gone out. If it's a compressor or a part within the flow of coolant, it can be expensive - it usually means replacing the compressor and disassembling the works, blowing it out, and replacing the filter, etc. Can be over $1k depending on what it is. BUT it can also be much easier. I had an '05 Volvo where after 20 minutes the A/C would go out. After determining there was no leak, I did some reading and found out the electromagnetic clutch on the compressor has shims that allow you to adjust it. I was able to adjust it in about 20 minutes for free.
Bottom line, before giving up hope, might try forums for your make / model car and see if there is an easy fix without throwing in the towel.
