Ask a Repair Shop
I did this when I was choosing a laptop. I called up a few laptop repair shops. It as so helpful! They could tell me what was junk and what was OK.<p>I also do something like this this when choosing a new ISP. I call the support line instead of the sales line. Somehow ISPs can answer sales enquiries instantly while support calls take 45 minutes to answer. This strategy has led me to use some of the smaller (slightly more expensive) ISPs, because I know they'll answer almost straight away.
