Need to upgrade Dell Inspiron 1525 from 2 to 4GB RAM for a co-worker...

Hi all. Trying to upgrade this Inspiron 1525 to 4GB, but having some trouble finding some RAM configuration tools(other than Crucial's) that will work for compatiblity. I'm been using Google to try to find RAM that will definitely work in this PC. I've had trouble in the past w/ Dell's being "picky" on certain OEM's modules. I don't want to order something that "should" work based on specs, only to find it doesn't POST. Trying to keep it on the cheap as well, $50 or less I'm guessing. Any help/suggestions would be appreciated. Thanks
