Lots of us use abrasive wheel 'chop' saws - but that wouldn't work for you unless you can setup outside and off the driveway. They throw off tons of sparks, smoke like hell, really noisy and stink up a garage quick. I've also had friends use them in the driveway - and when the grindings get wet - they rust and stain the mad owners purdy driveway....

I use a cheap Harbor Freight band saw for the basic cutting jobs:

A bit slow - but if you use quality blades the final results are good IMO.
