The DD-RT software is crazy good, but the hardware in most compatible routers can't compare to what you get in the D-Link DGL-4300 and D-Link DIR-655.
The DGL-4300 uses Ubicom IP3023 processor @ 250MHz with 16Mb memory. The DIR-655 uses the newer IP5160 processor @ 275MHz with 16Mb memory. The wire routing speed of those multi-threaded chips is 5x to 6x that of the Broadcom 5352 used in the popular Buffalo G54 routers. You probably won't notice a difference with a 5Mbps network connection, but you probably don't want most of the DD-RT compatible routers if you've got a 50Mbps network connection.

If wireless performance / range is what you want -- rather than maximum possible broadband throughput with faster connections and QoS -- then you should probably save yourself some money and opt for the Buffalo WHR-HP-54 with custom DD-RT firmware. You'll get superior 802.11g range with the Buffalo and DD-RT.
Note the D-Link DIR-655 is on sale for $99 as well, but the firmware on that unit isn't as mature as what you get with the DGL-4300, which has improved significantly in the past few months. The current firmware on the DIR-655 is also limited to 120 simultaneous connections, compared to 180 on the DGL-4300, which may impact torrent throughput.
