The Pioneer TX-940 looks pretty good when modified to have a blue display, to match other vintage fluoroscan gear.
I also kinda like the TX-710 and TX-720. Not my favorite style of tall buttons, but looks good to me. Matches the DT-500 and DT-510 timer and the RG-2 expander at least.
But my favorite by far is the TX-D1000. That's how a tuner is supposed to look (to me). (I really do love the blue fluoroscan)
I modified the TX-940 because I wanted a nice low-profile tuner that got good reception and matched my RT-909 and CT-F950, and the TX-D1000 is very difficult to find on eBay. When it's there, it sells for reasonable prices, but they don't come up that often.
I also found the TX-940 is a really GOOD tuner. It gets great reception. It has far better reception than the TX-950, the TX-720, my Toshiba ST-335 (which is no slouch, actually), my Phase Linear 5100, or my Kenwood KR4070 receiver. I'm hoping a little fiddling with the TX-720 will get some better reception though, I have a service manual in the mail...
