The best place for tuner information is to join the yahoo FMtuners group. I have a Mcintosh MR67 tube tuner and really like it. I was looking for either a MR67 or MR71, but got the MR67 because I found one in mint condition. The McIntosh tuners sound great, hold their value, and you can have them serviced by either Terry Dewick or Audio Classics.
A good place to buy tube tuners is actually ebay. Search for the model(s) you are interested in for about a month to get a feel for price and the range of conditions. Best to wait and bid on one that is in really good shape. Mine still looks brand new and it is 40 years old!
