Holux GPSlim 236 and 240 were both highly recommended AND reasonably priced, when I was buying a GPS for my N73 a few months back. I got the 236 and a buddy got the 240. No problems, except that if the gps unit hasn't been turned on for a day or longer, it can sometimes take it a few minutes to figure out where all the satelites are and lock on (i've never had a gps before, so not sure how normal that is), otherwise it's great. The battery lasts about 10 actual hours, I charge it once a wk or two now.
