always been interested in geocaching and i would like to start with my 8 yr old son. Any suggestions about used GPS's that would do the job in my 150.00 price range?
Andre, A used LegendC or VistaC would fit your requirement. We have a couple - I bought one on EBay for $100USD last year that we use for students (middle school exploratories) and adult continuing Ed. You can load caches and maps and they're easy to use. The young students get the hang of them very quickly. We were working our way around the classroom, showing them how to manually enter the coordinates, and the last group had already figured it out by the time one of us go to them
. The only issues we have (and it may be a big one for you) is that we lose satellite reception in the heavy canopy of coastal forests and the Legend and Vista take longer than the newer units to lock a location with the satellites. It is a good entry level unit though and works well in light tree cover. Our experience with them losing satellites is from the coastal rainforests of Vancouver Island so if you're in the interior it may not be an issue.
I'm not sure what a used 60CSx would go for but it would be a considerable step up to a very fine unit that holds satellites almost anywhere except the middle of Costco and gets a satellite lock much faster.
