Its pretty heavy, so i think it would be expensive to ship.
As for buying a new one, i'm not sure if its still made or not, but it is made by a company called Datum, it was designed for a computer/ control type center. It was designed to have data equipment and monitors mounted to it.
Not sure of the original cost new, but i think it was fairly expensive.
I would love to buy it but I a little far away. Well...only 2 1/2 hours. You would be surprised how much shipping is. I mailed some that was 5lbs ups and it was $15. Then I mailed something that was 25 lbs and it was $16. Kinda ridiculous but what are you gonna do.
Just out of curiousity, how well do you think this think would stand up to having a keggle HLT with up to 14 gallons of water up top? You mentioned planning it for a 5 gallon system, I'm wondering if it might stand up as a 10...
