I just got my Garmin 60cx a week ago, and I am loving it. This is my first year digging, and I thought what a great way to 1) not get lost, and 2) keep track of all my seng locations. The 60cx will run you $225, and is well worth the money. I have read reviews and done research on just about every handheld out there, and this is the best bang for your buck. Most older units won't be very accurate when it comes to setting waypoints, as well as horrible LCD quality. The 60cx holds 1000 way points.
I say go for it get one, it'll pay itself off in no time!
