While attending the Prop Expo a couple weeks back I had the pleasure of meeting Robert (aka RobotWorkshop on the Parallax Forums). Robert has a cool little kit, at a good price I might add, for the SX48. The module is a 40 pin DIP module with a MAX232 IC (for RS-232 com), EEPROM and a 20MHz. resonator.
This kit looks fairly easy to assemble and should be a good introduction to surface mount soldering as Robert told me. Here is a picture of it. You can find more information on this Forum Thread.
