Code Scanner recommendations?

ok...this time the SES light on my 2000 Jimmy won't go away. It has always disappeared after 2 or 3 days in the past. The truck is approaching 75,000 miles so it's time to buy a code scanner.

Does anyone have any recommendations?

I have been looking at the Equus 3100, but I'm open to suggestions. I'd like to keep the price under $300 or so.

Any help would be appreciated.
