One problem I see on many bandsaws is the table is not very rigid. If you can flex the table by hand a visible ammount, it's not good enough for metal cutting. Also, you'll tire very quickly of changing the blade over, setting the guides, etc, when you change materials being cut. It sounds like the machine you're looking at is not a heavily built one, re your comment about the heft of the metal bandsaw. If you're looking at the smaller version of a wood-cutting bandsaw, eg something that is lighter than the small metal bandsaw, beware, it could well be barely adequate for wood or plastic. Another thing, is the table aluminum? My experience is that aluminum tables don't go well with cutting aluminum.
