Because I wanted to be able to trade (and use my laptop on the road in general), I switched to Sprint PCS (from Verizon), bought a Sanyo 8100 phone ($100 with a one year contract), and FutureDials SnapDialer and cable (about $80). I'm clocking in at 115 kbs, which is a lot faster than a dial up (28.8 kbs), but not as fast as DSL or cable (200 to 500 kbs).
The signal has been very stable, no problems if you don't move around, and are in an area with good reception (digital signal).
The limitations of course are that this works only if you travel within the U.S., and are in an area with a good digital signal.
