It's a great saw - very commercial -- not a cheapie POS...
I bought it at Trick Tools... for around a grand I think. It's been GREAT! It cuts like butter - and is big enough to do "most" of what I need done. You'll have to check out the specs to see if it will cut big enough for you. All of the bigger saws I looked at took 3 ph -- and I just don't want to be "bothered" with doing a convertor and all that... so have other saws to cut the big stuff - but they make a HUGE mess -- and this saw is clean - quiet - and so fast to use. It is liquid lubricated - but has it's own "pump" and reservoir - which I already abandoned in favor of my larger 7 gallon reservoir and electric pump... but that's a separate issue.
I have blades for SS - Mild and Aluminum.... can't cut different metals without switching blades - ask me how I know this...
