For your first tuner, I'd suggest that you go with whatever you can get at a good price. Typically, I'd expect that to be a digital tuner from a major manufacturer. In this area, they appear to be pretty common and show up all the time.
I've found several digitals' at local thrifts that were in mint condition and only set me back $10/ea. One is a Pioneer TX-970 which is excellent and the other is a Denon TU-400 which is mediocre, but satisfactory. I also own a Yamaha T-960II that I bought new some years ago and a Sony ST-J55 that I was given. All of these tuners perform very well on the common wall-mounted dipole antennas, but IMHO the Pioneer and Yamaha seem to have the best sound quality of the bunch. In my experience, none of these units drift off frequency or have much of a problem rejecting interference from adjacent stations.
Comparing these digital tuners to several vintage analog tuners that I own feels alot like comparing apples and oranges. My analog units include a McIntosh MR-77, a Kenwood KT-7500(?), plus the tuners in several Pioneer, Kenwood, etc. receivers. In all cases, these analog tuners will drift off frequency upon occassion and do have some problem with adjacent frequencies, but all seem to have excellent sound quality. IMHO the McIntosh MR-77 is the best tuner I own and has both selectable stereo filters and selectable muting and superior sound quality.
Here in the Bay Area, FM reception is very easy to get, so tuner sensitivity isn't a real big factor. Also, there is a large number of FM stations here, so the big challenge seems to be selectivity, which most of my digital tuners seem to be very good at. While my analog tuners can drift off station and be a little bit of a challenge tuning in and isolating weak stations, the sound quality is excellent.
So, the absolute best tuner for you depends alot upon the state of FM broadcasting in your area and the challenges you'll face getting good reception and sound quality. I would again suggest that you go with something inexpensive for your first tuner to get your feet wet. With quality FM broadcasting become more and more scarce, you may well find that there is truly nothing of quality available to listen to.
Best of luck with whatever you chose!
