I don't think it's deceptive. It's pretty clear what you're getting. I haven't used them, but I have thought of it and perused heir site. You're right that $5 for 30 seconds is usually just going to pull you in to spending more for a whole 3 or 4 minute track, particularly if it's something like bass, but it's still not bad value if it's any good. On the other hand, if you're going to end up doing that for all the instruments, you might as well get a Nashville session outfit to do it.

I would think that this kind of thing comes into its own when you just need a solo, maybe sax or fiddle. Or maybe something like an instrumental tune that I have for the violin. I already have it with BIB backing and a midi violin that sounds like crap. If I can pay a violinist to re-record that midi violin with the real thing for$35, that's a pretty good deal. I might just do that.
