If you're looking to find your buddy's hunting spot which you've never seen before, in the dark, WAAS is a good thing. If you're out in a boat and very fogged in, to the point where you can't see past the siderails and every horn sounds like it's coming from anywhere, WAAS is a good thing. If you want to find exactly where you buried the fortune you took out of the stock market at the end of the 90's, WAAS is a good thing. Those are things that 3m accuracy would be very helpful for.

5-10m accuracy, which is non-WAAS attainable in most any conditions, is available on the $100-$175 models. I have a non-WAAS Magellan handheld, and with a smidgen of common sense and a topo map, I do really well. If I didn't want to, I wouldn't even need the topo map, but I've found that the two tools in conjunction really help when scouting and hunting. Garmin is a very reputable company, and I like their e-Trex designs, but there's so many of them I get them confused. My gut tells me that $175 is the cheapest you'd see WAAS-enabled handhelds, and maybe not even that cheap, but the prices have fallen so much in the past 5 years (I got my GPS 5 years ago) I've lost track.
