Okay, just bought them and spent another $10 for the vent-mount when I'm using the Dakota in the car. BTW, when I've got the GPS connected to my computer via the USB port, is it powering the GPS at that point too? Just wondering if I'll ever actually need/use the AC adapter. But hey, for the extra $2 it's not like I needed to do much research in advance to justify the purchase.

Any reason I wouldn't want to get these for $10? http://cgi.ebay.com/Garmin-Dakota-20-GPS-W...=item4aa39652fc All I really was looking for was a basic means to power my Dakota through the cigarette lighter when in the car. I figure for a couple extra dollars it wouldn't hurt to have the 120V connection too. And yes, I do realize that the Dakota doesn't have the means to re-charge the batteries through the unit, but it seems these things are called "chargers" regardless.

I was just reading about that - I think it was a rather thorough review by some engineer who posted his findings on Amazon. The other finding seems to be that the overall life-span of the NiZn's is rather limited as compared to NiMh. Somebody needs to make 1.5V Li-Ion AA batteries!

Right, Li batteries are NOT rechargeable; Li-Ion batteries ARE rechargeable. What sort of life are you getting out of the NiZn's in the Dakota?

My Dakota 10 just arrived and now I need to decide which rechargeable AA batteries to get. I had been thinking I'd get Li-Ions but I'm only seeing those in 3.6V in the AA format, which I presume won't work, correct? Assuming Li-Ion is not an option, I'd probably opt for the PowerGenix NiZn based on what I've read here. Anyone with any negative reviews on those, other than the fact that I need to get another charger? Feel free to make any other suggestions.

I need to correct what I wrote here. It appears that the standard "Bike & Hike" bundle includes the City Navigator DVD. I've now found it as inexpensive as $184 shipped. Seems like too good a deal to pass up.

Thanks for all the feedback. I'm thinking that elevation accuracy +/- 30 feet won't be a concern for me - it's more for novelty purposes of knowing how high I climbed. If the actual price delta was $50-75 indeed I'd be inclined to go with the 20. But with the promo they've got going (check the link above), that includes the Navigator software, it's more like a $200 delta, roughly double the price!

That's one of the other differences between the 10 and 20 - the 10 does not accept a microSD. But does it matter for my needs? The 10 comes with 850MB built-in. Here's the bundle I'm looking at for $219: http://www.tigergps.com/garmindakota10bh.h...CFQ2e7QodvlqGOQ Note that it includes the City Navigator DVD, which otherwise sells for $100. I'm not seeing anyone else including this in their bundles.

I've finally decided to get a GPS - yes, I'm late to the dance - I don't own one at all despite being a runner, biker, hiker, and field sales rep. Go figure? It seems to me that the Dakota form factor fits my needs best - I'm not a geocacher but probably will become one on occassion. The smaller size of the Dakota seems like a good "fit" for the bicycles, yet the screen size makes it usable in the car on occassion (I usually know where I'm going). Here's my primary question in trying to decide between the 10 and 20... Will I still get elevation data with the 10, or do I need the 20 for that? I don't require super accurate elevation data - it seems that's the incremental advantage that the 20 offers over the 10, but I want to be sure I get basic elevation data. Any input appreciated.
