It looks like I'm getting a new GPS. Rather than pay for a computer I'm building, I'm getting a Garmin GPSMap 60C plus United States TOPO and MetroGuide USA. I don't know much about this stuff, is it good for hiking? Does the Topo software have accurate trail locations or is there a way I can download more accurate trail info? I have a Garmin Etrex now that I barely use.
A quick look at the Garmin website shows the 60C to be a discontinued model. It has the older GPS chipset which is not as effective under tree cover as the newer "high sensitivity" models. I suggest that you consider the 60Cx or the 60CSx, both of which use the (high sensitivity) SiRFstarIII GPS chipset.* The *x models also feature a removable data card which allows one to put in up to 2GB of map storage. (The 60C has only 56MB which can easily become an annoying limitation.) FWIW, I have something like 1.3GB of topo and road map loaded into my 60CSx.
* The high sensitivity GPS chipsets significantly reduce the need for external antennas. (In general, I don't need/use mine unless I am specifically mapping a trail/route.)
The (Garmin) US Topo maps are based upon the USGS 100K topos and are generally accurate, but are a bit dated. This product is recently discontinued (still available in many stores) and has been replaced by the US Topo 2008 map product, which appears to be an improvment. (I'm considering upgrading.)
Garmin also has some 24K topo map products for selected areas (national parks plus some popular hiking areas (eg WMNF, Daks)). If you want more detail on more up-to-date maps, these are worth considering if they cover areas which are of interest to you.
FWIW, I have Metroguide 4.02 (road maps, discontinued), US Topo, and 24K East topo maps.
Re Garmin's road maps: Many of the current products are locked to a GPS (ie you must register them and Garmin will give you an unlock code for 1 GPS.) You cannot move them to another GPS without buying another unlock. Also, in the past, one or more of Garmin's roadmap products would autoroute on the computer, but not on a GPS. If you want to autoroute on the GPS, make sure that the roadmap supports autorouting on the GPS.
