I am biased since I am a dealer but the 10X4 is one of the best values in phono cartridges I have ever come across. I really like it a lot - and we typically do bundle it with the P3. I think the two make for a great combo.
I have not found that the 10X4 requires VTA adjustment on the P3 - typically when I mount the cartridge it is spot on. Nevertheless I am a big fan of VTA adjusters because they offer flexibility for future cartridges, and for the various record weights (i.e. 180 g, etc.) out there if you want to compensate for that.
But going back to the 10x4 for a moment, Twl is definitely right... it will smoke the BPS.
