I started out about 7 years ago with a Tradesman that I got from Ace hardware ($100.00) it used pin blades and vibrated so bad that I had trouble keeping it on the table. I used it for about two years (not knowing any better)
A friend recomended trying a Dremel from Lowes ($200.00) and I thougt it was the "cats meow" for 3 or 4 years of use. It did serve me well and I learned to love scrolling again.
Then I found this web site and Steve Good (and another friend) convinced me to buy a DeWalt. I saved my pennys, looked for the best price, and found it at Grizzlys on sale for $450.00 or so!!! WHOW!!!
I'm sure there better saws around but, the prices are out of my range.
As was said before "You get what you pay for" so take this for what it is worth from a happy scroller.
As time an money permit, I highly recomend a foot "dead man" switch, an auxriary light or two and an "easy lift" for the upper arm. Sure makes life worth scrolling!!
