Should've mentioned I've no experience of the unit. Just saw it mentioned on here a few times and seen the Go Outdoors flyer just in case it was a bargain for someone
The etrex 20/30 look very nice and a nice upgrade on the old HCx models (high sensitivity receiver, c = colour i.e. 256 and x = microsd slot). I'm not sure they are worth the money either though. I got a dakota 20 as the price was a lot better. The 10 is not really like the 20 and 30 it is monochrome and more like the lower level etrexes of old but updated (these can be got for fifty of sixty quid). In contrast the dakota 10 is very similar to the 20 (there is no 30), but has no SD card (but an adequate 850mb for OSM), not barometric altimeter and no electronic compass. Despite this the 10 is probably a pretty good buy for some of the prices it has gone for occasionally the last few months.
The etrex vista hcx and dakota 20 side by side are quite interesting. 256 colours worked very well for what it was with the old etrex but the slightly bigger screen and more colours on the dakota does make a big difference. The maps look much more natural. The extra configurability of the computer functions is also very nice.
