i've never had any interest in a chop saw, but from the looks of the replies here, i guess a lot of people use them. for the last 15+ years i've used one of the harbor freight metal cutting band saws. i think they retail them for around $200, give or take. it's most likely the same saw that someone posted about earlier that they got for $150ish. blades are about $10 each. they leave a very small kerf and they make very little noise, with no dust or sparks in the air. i just recently saw virtually identical ones at a tool dealer made by jet and a couple other makers. they really looked identical.
i wouldn't hesitate on the harbor freight brand though, it seems durable enough. the only thing i wouldn't buy is their blades (or any cutting and grinding consumables, for that matter) i bought 6 blades for a total of under $10, and they are too soft. i don't think i could break one, no matter how i twisted the blade, but they almost have to be forced through the metal. my local home depot stocks delta 64 1/2" blades for the saw at around $11, and they work much better.
