I like my Garmin76map.
It's bigger than ETrex, larger screen, one hand operation, waterproof, floats(!), NAVAIDS, TIDES, all possible readings, including VMG, ETA, Time traveled, distance traveled, distance to next, name it and you'll get it
And you can configure what to display, and what to hide. It burns 2 AA batteries in 13-16 hrs.
Unit has a base map, not really accurate, but you have two options with uploadable maps
One is "Garmin Lights and waterways" CD, around $40-50
Accurate coastline, islands, inlets,bouys, etc, no depth readings(it's a map, not a chart) and software for home PC.
You can create routes and waypoints in front of PC, then upload it to GPS. And you can download your track from device to your PC, create a picture and post it here

Second option is "Garmin BlueCharts" - pricey piece of software to get acctual charts to device - never used it yet

Device may be overkill for daysailing but I do a lot of cruising, sometimes night sailing, and I can't imagine myself without one.

Garmin also has a good non-warranty repair program. Once my GPS got between my knee and crossbar during exidental jibe. It kept working, but screen was cracked and half blank. I got replacement for $100, wich is flat fee for 76Map repairs.
I've never sheltered device and it has survived a few capsizes and a lot of spray...

P.S. It would be nice to have spell checker, it seems I'll never learn English
