A heads-up on a copy of PSP v. 5 available at eBay for $6, expiring in 8 hours. I started with v. 4 and loved it (they're now on v. 8). If you're interested, check the PSP website to make sure that current OS such as ME, XP, etc. support it. The guy only accepts money orders or cashiers checks, but for $6, you can't go far wrong.
