As mentioned above, if it's 'your' sound, you're quids in. I bought a second-hand one to try it out, and the next day, with Behringers 'quality issues' at the back of my mind, went out and bought a new one. Five years later, I'm still using the second-hand one, and the new one lives in my Gig Bag, just in case! Something I feel I should mention though, is that the Youtube videos don't do the pedal justice. It's much better in the 'real world' and in a Band situation, it really comes into it's own, to the point where, on Dep Gigs, I've had compliments from other Band Members on my sound.
At that price, you have very little to lose by trying one, to see if it fits you and your requirements.
(I've never played through a Sansamp, so the above is all IMHO)
