The 430s seem to go anywhere from $5,500 to $6,500 depending on condition
and who else is bidding.  There are fewer 340s, but I have seen them there.
They often have 530s as well.  Don't forget you will need a 14/28 volt
converter to power a 430 or a 530

430's newer than 2 years old do not require a converter to operate on 12 volts.  The software level should be 22 - If you buy such a unit, make sure an avionics shop brings it up to the proper level.
