low profile tuners?

The Sony XDRF1HD. Very compact, looks pleasant and has outstanding sound with great reception. The HD capability is a blast too. And it is a bargain. I've had mine for about four months and use it 12-14 hours a day. It's been nothing but a joy to have.

I have a Luxman TX 117. It stacks up well in the shootouts. I enjoy the sound quality and it is quite slim in profile.

I've been very happy w/ a Denon TU-767 in a rack w/ a NAIT5 (I think there were also lower Denon models w/ the same profile). It was a very-well-reviewed unit in its day - mid 80s.

If you want a great analog FM only Nikko Gama 1 is a great one there are a few listed on Ebay check them out.

The Linn Kremlin is about 3" in height and it's LK box is small and fairly unobtrusive. The reception and sound is stunning. And they are going for around 1/5 of their original cost used these days ($1000 - $1200).
