I purchased my 500 through REI in April 2007 on sale for $189.99 with a coupon also for a Li-Ion battery and charger. Magellan is back ordered for my battery and charger- just about ready to order another battery else where for the time being. I purchased a car charger so I could still use the Li-Ion battery. I had problems with the SanDisk 256mb card, but went to the local Radio Shack and purchased another one for the same price of $19.95 that had 1gb of memory.
