Maybe my google "profile" is not giving me hits, but there isn't anything I get (except one site listing the Kraft amongst the low- to-middle priced saws - but no other detail. Can't find the manufacturer's site either?! Hmm.
That said, there are a number of people who write about the Ryobi for instance, and say it vibrates all over the place, its knuckle-busting to change blades, the cuts are rough, and many can't wait to get rid of it. Had a look at the Ryobi in a store this afternoon, and the actual unit *looks* quite nice... lol.
I don't want to get mad with myself SO early in the year for a hasty purchase which ends up being a frustration to use. Rather wait and get something nice.
I hear you about the blade quality. I have found a local supplier of those F.D.'s here. They seem like favourites on the scrollsaw-type forums. [a funny thing is that I've asked this same question there - and no replies lol.]
