For the bux, I'd go for it. I've bought a number of Agiles from Rondo. I don't know if you can tell, but I'm stoked on Agile. If the SXs are anywhere near the same value, you will be very happy. From what I've heard, though, you may have to do a bit of tinkering to get the set up sorted out. Get one and let us know how they are. If it really sucks, you can probably return it. Bargains rock, and half the excitement is making it better, and making it yours.
