@stewblack, they’re honestly great basses at every price point. Speaking only of the current range, if you’re a passive kinda guy the 434/435 are near impossible to beat for the price in terms of build quality and sound. If you’re generally more of an active bassist, the 734/735 build on the existing brilliance of the 434/435 with different finish options and an (in my opinion) excellent preamp.
I can’t speak from experience on the P34/35 series but there are plenty on this thread who can!
