Only used a Vermeer SC130 for one day when my 252 was down a few years ago. Seemed like alot of work for little return, had dull teeth and made finer chips than a tablesaw.
Anyway, I opted for the Alpine Magnum instead of a walk behind for all the hard to reach stuff. No regrets, at 90 lbs it goes anywhere, easy on slopes. I can't imagine trying to manually swing a walk-behind on a slope. Once the word is out you have one the work seems to snowball, it has for me. I haven't gone back and totalled all the invoices on jobs I used it on in the last two years but I'm sure it's at least paid for itself three times over ($4K was original price of machine). That said, it does give you a good workout, so it only gets used when necessary.
