I had one and brought it back because tha Batts where so expensive- But i found a cheap store shortly after- still, its not cheap to run it every day.

I emailed plantraco a while ago, and they stated that they are currently testing a prototype, but it will be a while untill the minor bugs are fixed, I believe to remember it was a problem to adapt t to their Lithium Charger Plug or something, maybee it was the chargers range of volt/A.

Regular NiCd or NiMh Recharg. would not be much fun, since the Lithium-cells have a much higher capacity- but cant give off as much energy as others.

I hope they will soon have them in stock, since I shortly had the whole set (with cam), and it rocks- now they even have the webdemo with the rovercam (which is pretty slow and irritating- still, nice! ;D )

Oh, btw, I started a Yahoo group for the DR a while ago, not much going on though :-(

If the DR will be available with Li-Recharg. I will buy it and install a similar thing like the rover demo- maybee just in my whole apartment ;D I hope I dont step at it .

One thing I noticed while I had it: It tips lots easier then on the webdemo- they use some kind of thicker wire so it rolls over/doenst skip as easy....

any details on that?
