Well, unfortunately I'm going to have to decline to make specific brand and model recommendations. My salary is paid by an outdoor retailer who sells GPS receivers. If I offer public recommendations on which particular receiver to buy, I risk irritating my employer, their competitors, and the TradGang administrators, mebbe all at the same time.
I can reiterate the earlier recommendation for a site crammed with current GPS info:
gpsinformation.net . Lots of reliable, specific info, although it needs better organization.
