Bought a Palm M130 on eBay for $40, and a new - higher capacity battery for $8. Replaced the battery myself. Works GREAT with Cachmate and GSAK. Currently have 6000 waypoints AND cache info AND the last 5 log entries loaded on a SD card for the PDA. Great for paperless caching. That's all I use the PDA for, except sometimes making notes.
