[Cdt-l] GPS and Maps (howzit done?)

Thanks for the helpful advice ya'll. To summarize some of what I've learned:

- The Garmin Colorado/Oregon GPS have added value as they include 100k maps at no extra charge. 
- Everyone that commented had used 100k maps, no one had used 24k maps. 
- Don't buy the preloaded microSD cards. Buying the CD and loading your own cards means you have a backup for the maps if you loose/damage the microSD card. 
- Out of Order's track file of the CDT is great, and can be sent to you by email from people on the list.
- There are free 24k maps available from http://www.miscjunk.org/ 

Some further questions....

- Really? Everyone uses 100k maps? It seems like the 24k maps would be SO much better. 
- Anyone have comments on the 24k maps from miscjunk.org ?
- Can anyone tell me more about Out of Orders track log? How come it's not available online?

I haven't read Yogi's comments on GPS as I'm waiting for her to update the guide. But I'm buying my GPS before I buy the guide. Anything in there that is important to know?

At the moment, the options are looking like:

- Colorado 400t is $300 on ebay, and I'll just use the preloaded maps. 
- The Legend and Vista end up being ~50-80 cheaper after I buy the 100k maps.
