I have 12 FM tuners here. 3 Sony ST-SA50ES, a Sony FDR-F1HD, a Marantz 115B, Marantz ST-17(B), Marantz ST-7001, Onkyo T-4555, Parasound PD-Q1600, Yamaha T-07, Yamaha TX-330 and a Denon TU-1500RD.
Of all of them, the top three are the Sony FDR-F1HD, the Sony ST-SA50ES and the Marantz ST-17(B). The cheapest to be had on.....say eBay is the Sony-STSA50ES. Its a very quiet tuner with great capture ratio. low noise and low distortion. The most I paid for the ST-SA50ES was $600 (new), the least was around $50.
Occasionally, you may find the Philips 920, but they are rare. Perhaps many are dead now. The ones that I have seen are really beat up.
Do not buy the Sony ST-550ES. They seem to have problems, but then they are starting to hit 25+ years old (or more).
The Marantz ST-17(B) is from the Seventeen series and it is the cream of the crop here, anyway. It's built like a brick S.H., the easiest tuner to move from preset to preset and is very musical, but, also very hard to find and they will cost you.
My 2 cents.
