I am not a big fan of the Pat 4 -- kind of transistory sounding, and the control pots don't have a good feel to them. On the other hand, it has good set of controls. The first Beta preamp was not in the same league as the later ones, the later ones being quite nice. Can't comment on the price, other than noting that the PAT 4 doesn't command big money (and if really cheap, and you are capable of modifying it, it might not be a bad pick up).
