Im sure others think differently, but this is kind of a hard call, you dont see too many series basses come up for sale, and the price is ALMOST reasonable considering that it has been around the block more than a few times, probably needs updated electronics, a fretjob, and god knows what else.
I guess you need to ask yourself if your comfortable paying that price for a bass that sounds like it may need some work, and a trip back to Alembic to have that done. If you dont mind doing that than go for it.
I personally wouldnt want to deal with the possibility of having to ship a bass back out to have work done it. Iwould wait and spend more on something that wouldnt need to be worked on right away.
