You might want to consider the Garmin E-trex series of receivers. Some of the higher end e-trex models such as the Vista and Legend will perform the basic requirements you are looking for, are closer to your price range but don't have all the bells and whistles of the 60CSX or Colorado.
The GPS will come with a set of 'base' maps containing major roads & highways. You should consider an optional mapping program such as Mapsource Topo 2008. The E-trex series will allow you to download specific regions to the GPS but the 24 mB (of the Vista) will fill quickly and you will only have the capabilities to use one map at a time.
There have been at least 3 models each of the Legend and Vista. The one with 24MB of map memory is obsolete.
All of Garmin's mapping models have basemaps and will allow you to download additional maps into the GPS. Multiple maps can be active simultaneously, but only one will be shown for a specific region (as if you laid several paper maps on top of each other--only the top one will show, but different regions may have different top maps).
Garmin's Topo 2008 covers the entire USA at 1:100K scale. Garmin also sells maps for national parks (including the Whites and DAKS) at 1:25K scale.
I would also recommend a 'x' model. These have an electronic internal dynamic compass and barometric altimiter.
"x" specifies a removable memory card. (Worthwhile, IMO.) "S" specifies electronic compass and barometric altimeter. (IMO, the altimeter is worthwhile, and a mechanical compass is better.)
Also the higher end models contain a SIRF chip which averages your position and can generally place you within 5-20 Ft of your true location.
All of the GPS chipsets have similar accuracy if you have a good skyview and the signals are not blocked. However, trees and terrain block the signals and degrade the performance of the less sensitive units. A high sensitivity unit is well worth the extra cost. Garmin sells units with one of 3 high sensitivity GPS chipsets (SIRF StarIII, MTK, and an internally designed one), as well as older units with less sensitivity.
* SIRF StarIII: 60/76 Cx and CSx
* MTK: H units
* internal: Colorado line
The 60CSx with Garmin Topo 2008 is a common configuration used by VFTTers. (It is a good combo for hiking.)
