I bought a Juki serger from them a few years back. The machine arrived quickly, as did most of the freebies that were supposed to come with it. I did have to wait about 3 weeks for the bonus feet that came with it because they were out of stock (not that big of a deal, I hardly ever use those feet anyhow). I wouldn't hesitate in buying from them again.
If you buy a machine online, you might want to make sure there is someplace local that can service the machine for you. I happen to have a Juki repair shop a few blocks from my house.
