At home I use 2 tuners, a Sony ST-SE570 Tuner FM/AM (Hi-Fi Seperate) and a Sony ST-SB920 Tuner FM/AM (Hi-Fi Seperate).
I use the ST-SB929 for DX-ing, with the use of modified filters (explained below)

The 920 is basically the same as the SE570, except it has dual antenna inputs and a narrow/wide filter selection option.

I have had my 920 modified (by Paul from the Skywaves irc chat) with 3x 110khz wide filters and 1x 80khz narrow filter. This improves selectivity alot - very useful if the band is full of local stations. It basically eliminates bleed from an adjacant station, e.g 96.2 Yorkshire Coast Radio - still heared on 96.3 with wide filters, with narrow filters you no longer hear YCR on 96.3, which allows for Radio Aire to be audible.

I've also had the tuner modified with a RDS cable, which is attached to my pc via a serial cable. With software you can view RDS information on the PC, you can also log this information. Generally PI codes are identified quicker with the use of software which is very usefull during DX. The software I use is called 'FMDX' created by Herman Wijnants and can be downloaded here.

And here are some pics of her.
