Hope it works out for you.
We took the bikes out last night for a spin after replacing the busted tube. I think the one we bought was of better quality (we bought a cheap one to keep in the saddle bag and a more expensive one to use).
Like I said before, a tube explosion could cause a serious accident if one was riding with any kind of speed. Luckily we weren't. I'm just hopin' that replacing the factory crap will be enough.
