Yep..... there a a couple others out there that have made their own. I sell these and to be quite frank, they are really good for edge work but there is a bunch out there that can do the same thing for less money. What this company is well known for are their vacuum systems. Pulse Vacs are really good for a non plugging vac system.... the are really proud of those too. As with anything, you pay for the better systems.
For someone that is doing this "just" for their own applicaion and not in the biz.... it's really overkill. If you want this, I'd buy it back for 75% of the cost.... if you purchase it through me. I'll give you the contractor discount.... something to think about.
