Recently my 2007 MPB suffered a torn screen ribbon. It works fine connected to an external monitor, so I'm thinking about investing a few hundred dollars to create a decent desktop (new monitor, keyboard and mouse). I don't care about losing portability, but I am questioning whether it's worth the money to create a desktop out of an older machine. I'm concerned about how well non-Apple external monitors work with MBPs. While I'm not looking for the same clarity as my MBP monitor, I'd like something relatively close. And, I'd like to be able to do it with a fairly inexpensive monitor. Once this "desktop" gets much above $300, I think it makes more sense to look at something newer like a used iMac. Are the stories about lack of sharpness with external monitors the exception or the rule? Short of hooking my MBP up to a bunch of monitors at a big box store, I'm not sure how I can figure out which monitors work well. Thoughts?
