Tethering a Venus I got about 700kbps. With a USB Modem (flashed) I got 800. Good performance for the price. I'm guessing you are talking about getting the usb modem or Laptop wireless card (Cricket branded). SpeeRAB should be about the same, but since the parts may be cheaper you might get slower speeRAB. Not sure really, just know that their network is pretty capable and moving to Rev. A EVDO by next year.
