I have an Explorist 200, which I love. I always take a topo map (and, by the way, if you haven't yet used mytopo.com, you're missing out bigtime) and compass, so I don't miss the inability to download maps.
The manner in which I use the GPS makes the issue of a PC connection moot. I don't need to see my previously-used route(s) or track(s) on a map, and I don't need to download multiple waypoints at a time. I use it mostly for casual geocaching and for hunting and hiking. For these activities it performs admirably.
I only look for a couple geocaches at a time, so entering the coord's manually is no big deal---very easy, in fact.
DO download the .pdf manual from Magellan's website and read it thoroughly to become familiar with all the features and to use the unit most efficiently.
I like the screen size, the display options, the small size and the ease of use.
I have found the antenna sometimes wanting under heavy tree cover, but I don't have enough experience with other units to know whether they would do a better job. On a recent hike I was under heavy tree cover in a deep valley and I had 4 satellites locked in. Ok, so the accuracy was compromised, but I had no trouble getting back to my car. I did, however, have trouble finding the cache, but I'm not sure that---under those conditions---a different unit would have performed better (although I understand a Quad-Helix antenna might).
