Victor-
An MR 85 can be had for a LOT less than $2000, but to be honest, the only reasons to buy one are if you want two zones from one tuner and to be able to use a single remote with the rest of your Mc gear. Don't get me wrong, it's a competent tuner, but it's not worth the price, even for about $1200 used.
Grumpy is right about vintage tuners being better. His TU-X1 will cost more than an MR85, but even fully moded a TU-919 will cost less, and will completely outperform the 85. Go to the Tuner Information Center (just Google "FM Tuners") and take a look at their rankings. The only difficulty I have with their evaluations is that for my main listening system, I insist on a remote, and few of the vintage tuners have one, including the Sequerra, it seems!
Good luck!
