What kind of GPS are you using?

I find that my margin of error for my cheapie Garmin unit is less than a meter and most times less than that.

I've got a cheapie garmin unit too :). Usually it gives the same readings at the same spots, but in one case was off by 4 meters, so I have doubts about the accuracy. A meter or two wouldn't throw me too much, but 4 meters is enough to throw off acreage calculations!

Just out of curiosity Rosa, do you use it for mapping contract sites? I had thought I might eventually do that before finding the sampling-error problem.

Can any designers out there recommend a graphics program to use with the coordinates? When I was in college I used Canvas (version 2.x). Is that still a good program, or maybe too much? I don't have any use for 3-D rendering or anything like that.
