If you aren't ready to jump on the bag o' tools that Ridgid is offering that has a multitool in it, you might want to check out HF's new variable speed multitool.
They have it on sale now and it is a pretty nice looking machine. Seems better built that the Rockwell (Sonicrafter ?) machine and comes with a pile of blades in a compact case. Sale price is $49.
I bought the single speed HF model for $35 about 6 weeks ago, and it has been great. Had I known how many things I could actually use this thing for, I probably would have bought the basic Fein years ago.
As a sidebar, I swore off any tool that looked even just a little gimmicky after I purchased the DeWalt model of a Roto tool. I used it once about 8 years ago. What a waste of time and money that was.
At any rate, the multitool machine they sell seems to run very well, has plenty of power, and I am hoping it is like the 4" grinder I bought at HF a few years ago. I just can't kill it. And it looks like the new HF multitool is basically the same machine as the old one, just variable speed + a case.
I haven't killed mine yet and it has trimmed a lot of 5/8" plywood siding, trim boards, cut holes for access, and even cut through several feet of very thick hot mopped roofing.
Great buy.
