Most likely the model you have will be A00A as this is the most common kit on the devkit "testkit", or A00J.
Prices are all around the 1400A regularly ranges about 350-500 depending on several variables.
The A00A would be about 250ish depending on variables, and a A00J would be similar to the previous. These are not guaranteed prices but what they typically trend around, you could get more depending, could be less I have no way of knowing. In order to get more out of these devices, there would have to be special exceptions such as unreleased content, CIB in immaculate condition and so on so it really varies on buyer and current market environment.
-Hope this helps, both kits BTW shipped with decr-1010 pads, though only some of the A00A/J models included them as they were often supplied with retail pads instead. Just a little tidbit of info any questions feel free to ask.
