I have had my Legend C since Friday, from GPSCity, and I am absolutely amazed (of course I did just upgrade from an Etrex Yellow that I have had for three years).
I bought it over the 60 mainly for the small size. I was worried that the screen would be too small to use but I am finding that it is fine for navigating in the car.
I am finding that 24 Mb is liveable and a fine tradeoff for price and size.
Reception is great. My Etrex got a good signal in the bathroom, yeah I know, of my one story house. The Legend C, however, gets a good fix in the majority of the house...so treecover doesn't seem to be a problem.
Let me know if anyone wants to know anything specific about the unit and I'll try my best to answer.
