The old etrexes are good units, but you do have to be careful on pricing because everything is in change now. The prices on various retailers have fluctuated and there has been a lot of overpricing of second hand units (including on this site). People seem unaware that they are old units and therefore not worth anywhere near what a lot of people are asking. They are still good units though.
The price of the new eTrex 20/30 vs the Dakota 10/20 is not consistent either. e.g the price of the dakota 10 has gone to back down to £139.40 on amazon recently (850Mb internal, no microSD).
