I assume you want transmit in the entire 29.7 to 50 MHz range but some of the other ham versions that receive this range and weren't mentioned, are the kenwood TS690, yaesu FT100D.
For tx in 29.7 to 50 MHz some choices are:
CDM1250 which will indeed cover up to 6 meters but it won't cover all of 29.7 to 54 MHz, they come in the classic 3 low band splits.
The only radios that do low band Transmit in one complete split are the Motorola Syntor and it's derivatives the X and the X9000. The Wulfsberg RT30 and RT5000, and some of the technisonics low band avionics radios (all very expensive).
Some of the military radios such as the Harris and other vendors PRC radios (equally expensive), the older Kachina low band man pack series of radios (hard to find and pricey) and some others that I can't remember right now but 5 minutes after sending this I'm sure I'll remember 5 or 6 others.
