OBD Scanners....

I'm thinking about getting an OBD scanner.... does anybody have suggestions/experience with them? (Eqqus, Auto Xray, Actron etc.). I've been reading about them, but I haven't seen any comparison tests.

i bought an actron at sears. has worked great. plug it into the diag port on the car, turn the car on to accessory and hit the read button on the scanner. it comes up with a code if any are there along with a short decription of the problem. you then go ot the actron website and plug in the code. it will give you a more detialed description of the code.
