I have an Etrex summit that I am hoping someone can use... works perfect...has software, AC charger, data transfer cable. Works perfect.... getting rid of it because I upgraded last month. A refurbished one on Ebay goes for around $100- that doesn't include the data transfer cable-that is extra... If you're interested I'd be asking around $80 for everything plus whatever the actual shipping costs, which I would estimate at around $6. If you're interested, or have any questions, or would like me to send some pics of the unit, just let me know. snail84@aol.com
