Hmmm...........no iwaver for me, then.

The tank on Ebay may or may not have as good of quality as the iwaver, but at least it is rechargeable. I hate putting money into AA batteries. [:@]
Rechargeable AAs probably wouldn't last as long or be as powerful as the 7.2v battery will they? The listing indicates run-times of up to one hour, but even if it is half of that, it would still run
MUCH longer than my E-Maxx.

It would also recharge in 20 minutes.
I have already bid on another tank....maybe this one will actually arrive.

I don't think I can afford one of the Tamiya tanks. [

The tank you linked to is much larger than the Iwavers. Iwavers are 1:24 scale... that one on eBay is 1:16 scale. You can get rechargeable AAs with 2500mAh capacity... I'd bet that's as much or more than the capacity of the cheap batt pack you get with that eBay tank. For a 1:24 scale tank... NiMH AAs have plenty of current output capacity...
