Hi Maning, I have a two week old etrex 20 and a Legend hcx. I know you were asking for the 30, but the only difference is the absence of the atmospheric barometer [1], magnetic compass, and the ability to connect to Ant+ devices.
the 20 was a clear winner for me since it was cheaper and the extra features of the 30 wont be hugely missed for mapping. Here's a good review of the 20 [0] but the reviewers firmware was 2.2. I havent checked if the bugs have been resolved in 3.0, but i share most of his experience with the device the hcx reports a better accuracy against the 20 (gps+glonass) with a good view of the sky. however, the 20 is only slightly affected when there are tall buildings on one side of the road. on streets with tall buildings, the 20 shows slightly more drift than the hcx. having said all this, i feel the 20 reports a more conservative accuracy and is a bit more transparent with errors in logging tracks. A colleague has a 62 (not sure which model) and he just agreed to lend me his unit next week. :) if you'd want some comparisons between the hcx, 20, and 62, let me know your questions.
