I've got the same setup Prism has ... Voyager 16 on a Hinterberg stretch frame. I also purchased mine used ... for a song!! Found it on Craigslist.
What I like about the Hinty stretch frame is that you can make it any size you want (it has an upper limit, I forgot what it is ... I *think* 10'). If you want it longer, buy longer poles. I made my own leaders for it as well, I used pillow ticking (because it's strong and already has the horizontal lines which I know are straight because they're woven) and I attached zippers to them.
The Voyager is a good machine as well, and I have the stitch regulator with mine. Nary a problem with it. A lot of people tell me they can't get it to run Aurifil thread with it ... I haven't tried it yet though.
