I’m selling my Garmin Geko 201 GPS plus extras on eBay (item 320106781450). I’ve been very happy with it, and the only reason I’m selling it is because I just upgraded to a GPSMap 60CSx. Dave has a similar unit, and I was very impressed with the way it handled routing when we drove around Vancouver.
Most of the reviews of the unit seem to be pretty on the mark: accurate location, quick acquisition, and an ability to find a signal with little or no skyview. While the 60CSx does appear to work indoors, it suffers from weird track jitter.
