The Accuphase looks like a very fine piece, especially being refurbished with expert care, but the price is too much of a stretch for me.
I'd be more comfortable under $300.
These responses have been very helpful and I am going back and forth between tuners for sale and the fmtunerinfo page.
Magnum Dynalab seems like a good choice and am keeping my eyes out for nice vintage, but it does seem that the older tuners especially, may benefit from some refurbishing and/or upgrades.
The hunt continues for now!
