Actually modifying the saw is not so hard, a buddy and I did one about 15 years ago, mount the saw to a 24 " square piece of counter-top material 1" thick, we used duraflake, pull the motor off, get a pulley the same size to fit your new motor, mount the motor on a platform that is mounted to the counter top material so it lines up with the motor hole and bam your in bussiness best part the saw it self has not been harmed and can be put back together and resold, this whole mod can be completed using nothing but wood and lag bolts in less than 2 hours
The cheapest vertical metal cutting band saw that I have been able to find so far is around $800, tools from harbor freight are a joke, I bought a belt sander from them, put it together, chuckled for a few minutes, put it back in the box and took it back, the vertical/horizontal saw they sell gets bad reviews, also I looked at one and it is cheap junk
Delta is a good saw, if you modify it, chances are you will be using it for the next 20 years, I have been a carpenter for 30 years and buying cheap tools has never worked out for me ;0)
