Hi, I'm new to this site and this is my first post...
I've used a Garmin Legend HCx for geo-caching since July 2010, and with it I've had more than 500 finds. I decided to change it for one of the new Garmin Etrex 20's just a few weeks ago. I've got to say that the Legend HCx is a very capable GPS'r. If theres anything that I can help you with then just email me with the details of what you're have problems with and I'll do my best to help. Loading geocaches shouldn't take more than a few seconds. Mapping is another matter that I can help with, full OS based UK maps can also be loaded free of charge - these are regularly updated too - all free!
Email me if you think I can help you.
Best regards,
