Is there a chart?

[NitroSteel]

I'm looking at getting a new GPS primarily for hunting.  I've had 2 Garmin's in the past, a 12xl and a GPS II+.  I'd like to upgrade to something with mapping, but I don't understand which maps come with the units, why others are for sale, etc., etc...

Is there a chart that shows different features, so that I can get the least expensive one that fits the bill?

I don't think it really matters if I go with Garmin, since none of the newer models will work like the one I have.  Is Garmin still the best brand to buy?

I mostly want it for hunting out west in CO, WY and NM.  But I also hike in GA and NC.  Do any of the GPS's setup with Topo maps come with streets built in also?  Can it be added?  The Colorado 400t by Garmin looks really nice, but I'd like to keep it down in the $150-250 range if possible.  I don't care anything about 2 way radios or transferring information wirelessly...

Thank you for your help.  Sorry to be so ignorant.

Here's one that compares several makes:

It may not be comprehensive, but it's the biggest list I've encountered.

Another GPS receiver at the top of your stated price range is the DeLorme Earthmate PN-20. You can find out about it at their website www.delorme.com . At www.garmin.com , there's a comparison feature for their own products.

I use a DeLorme PN-40, which is a '20 with a couple o' bells & whistles added. It came with a topographical program that you can put on to your computer and also 3 CD's that encompass topographical maps of all the states that you can put onto the PN40's internal memory or onto an SD card that fits into a slot in the unit. I think they're a somewhat simplified version of those big red DeLorme atlases of the states that you see in gas stations & bookstores. (If you want USGS topo maps or aerial maps, you have to download them with the topo program that you put onto your computer.) The PN 20 probably behaves similarly.

Those topo maps that come with the DeLorme Earthmates will show you the street names when you're on the road; you can even set up a road route to follow. Unfortunately, the DeLormes don't have that sultry Garmin wench who'll tell you when to turn.
