Mike,

A GE Delta/Phoenix/Rangr can provide up to 32 channels / 5-bits of 
steering, with two X2212 memory chips installed, or any number of channels 
with an after-market X2212 replacement board installed.

A Motorola MaraTrac can provide up to 99 channels.

A Kenwood TM-281A may be your best bet, but I haven't personally tried 
this radio, yet.
