I had that problem, and I sent mine in for the $150 repairs. I justified the fixes because I definitely play it often enough. Plus, there are console and PS3 exclusives that I want and look forward to playing. Additionally, I just prefer to play some types of games on console. For example, NBA 2k8,9,10 and Burnout Paradise. If you don't think you're going to want to play many games on the console, then it might be better off to go all PC. It sounds like you are very reluctant to pay for the fixes so maybe you could buy a Blu Ray drive and try to fix it yourself.
