No, but HockeyNut's would be worth the money. No wobble but the whole thing is the typical pressed board. It works and for the money it isn't bad. I never saw one pre built but it all depends which one the put together at the store there might be a similar one you can see.
No none. The only issue that I have with it is that it is made out of pressed wood like all furniture these days and you don't really want to have it be wet.
