I know that this thread is old, but wanted to chime in. I had a forerunner 101 before I started caching, so used it when I discovered the sport. I do a lot of this on horseback, and love that the 101 has the wrist strap that attaches to my saddle. For Christmas I gifted myself a new Venture HC, and I can't decide if I like it. I like that I can down load the data, but the data is incomplete (no hints, descriptions, etc). I also don't like the screens--I miss the map + compass screens being combined, and really miss the "list of nearest caches" screen. No sure if I'm keeping the Venture or sending it back. Definately keeping the 101, which seems to be nearly as accurate, and atleast doesn't guess at locations when under tree cover.
Hope this helps someone...
