We have been Geocaching for a month. Bought an iFinder and started right out. Don't have much to compare it to, but it works great for us. The only negative is that, because it does not accept serial data input, you can't use EasyGPS with it. However, this has not been an issue with us.
The mapping features of the iFinder are very nice. You will need to buy the following to get the detailed maps, assuming that you just bought the basic model:
MapCreate6 ($130)
MMC Card Reader ($35)
MMC Cards (32MB recommended) ($25)
