Thanks @chayro, I may have to keep the shelf, although I am trying to minmize things.
And thanks @tablejockey and @ojc. I agree, my first inclination was to in fact purchase the P10 with the Apheta 3 cartridge. The ease of set up, as well as synergy between the cart and table seemed the logical choice.
But, the cost savings with the open box unit, using my current Soundsmith cart, and then upgrading to another cart next year seemed like a good plan.
It comes down to spending the extra $2,500 now, get a turnkey table with the Apheta, and leave it at that. Or save that money now, use my current Soundsmith cart. And next year have the option to buy an Apheta or maybe something further up the chain, in the $4K range.
