man, just get pinstripes and be done with it. they're very middle of the road in terms of "good sounding heads", but they'll do fine for a cheap kit. get a set of ambassadors for the bottom.
heads like the G1's and G2's (coated or clear) and such on the batter side of things will quite often make bad drums sound worse. i love em (they're WIDE OPEN sounding and have a very wide tuning range), but they're picky about having well-cut bearing edges and whatnot. you may find they're more hassle than they're worth.
even though pinstripes aren't the best sounding heads in the world, on a cheap kit i will recommend them every single time, b/c they seem to make bad drums sound better.
cheers,
