Good deal on cool tube?

OOPS! found the best deals thread! sorry.

I've been in the engineering/planning state of my secret project and I was hoping to get some community input.

I know that some people claim that ebay stuff can be good for some hobbies, but let me tell you what in the automotive hobby world ebay is crap. This seems to be the best price that I can find on a 6" cool tube and significantly cheaper then most of the popular hydroponic sites. any input would be great and I'm sorry if I posted this in the wrong area.

Significantly cheaper yes but at a friends Hydro store we have this chat with customers often as we have to embrace the quote we all know " You get what you pay for " ..

I see no details listed on the materials used in this cooltube and it would make one assume its cheaply made and probably wont be as efficient as the leading ones within the market .. Better safe than sorry and have fun dealing with any return or warranty work ..

I buy the virtual sun kit rip out the cooltube from the hood and use everything else
