Go check out a Bosch or 3. Head to Sears, they do sell "name brand" tools now too, so mebbe you can do a side by side.
Bosch invented the friggen concept and they've made almost all the enhancements known to the tool. Get nicer blades than the Vermont American's you've probably been buying. Those things are good for metal, where you just wanna throw it away when you're done, but other than that, the better blades will last longer too.
DeWalt makes 2 nice ones. (*edit* look in our project threads, I don't know the numbers offhand, but they're in there) The one I have, and Markrvp swears by his (the next step down in the DeWalt line). The one that's below Mark's is the one my brother-in-law has, and I'd have to give it a crap vote, although it gets the job done, it's just not worth the money in that range.
Compare the saws in the same price range. If yours seems better built, keep it. Brands are nothing more than something you stick with because you like their concepts. They generally indicate SOME level of quality, but not always, and who knows, you might be the one who gets the lemon, or the one who gets the diamond-in-the-rough.
There should be some information on the boxes/cases to use for comparison. Another thing, if you can hold them in your hand, a lot of times weight can be an indicator of quality (better windings, gearing, materials used, etc). Check it out before you use it.
