If you like the way your explorist 100 works, look into a the higher explorist models. I too started out with a 100, and am currently using an explorist 600xl. That is truly a very good top of the line GPS with a HUGE color screen, and extremely accurate. The regular 600 is a great model, and can be loaded with maps from Magellan. Look closely at the features you want, decide and enjoy. Just my 2 cents.

bnb is right, but be careful. I believe the cheapest explorist that you can download to is the 210. You can download to all the Garmin etrex models, but the plain yellow one does not come with a cable and you can only buy a serial (non-USB) cable, so if your computer doesn’t have a serial port, you have to go through some rigamarole to convert to serial from USB. You can pick up a third party cable for the etrex for around $10 on eBay. I believe the etrex Legend does come with a cable and is quite a bit nicer and only costs about $30 more, so with the added cost of the cable, ol’ yeller isn’t so much of a bargain. Also, Garmin does make a few GPSs without computer interface, (Geko 101 for example), so double check this before you buy. But there is no need to buy an advanced unit if all you want is a computer interface.

I did exactly what Wis Kid mentioned but I bought a refurbished Etrex yellow unit for the kids to use and got the cable off Ebay. Total 60.00 including the one year warranty. Nice inexpensive way to get a unit that you can download way points into.
