I've gotten a second opinion and it looks like my AC compressor does need replacing. The second place gave me a quote of $2,350 CAD, which is much better than the dealers $3,800 CAD.
The compressor is $1,700 of that $2,350. GermanAutoParts has it for $529 USD, so even after conversion, shipping, duty, etc, it should be about a grand cheaper. The shop said they're fine installing a compressor I supply, and the install cost remains the same.
Mark has replied to my from GAP extremely quick and been awesome. I'm always just cautious when a site offers something for so much less than others. For instance, ECS offers the same thing on sale for $875 USD.
Thanks,
