14 & 6.5 gallon carboys

Hi all,
I have found 3 14.5 gallon glass carboys for equivalent of $80 (for all 3) and 4 6.5 gallon glass carboys for $80 also,
I am limited to 6 gallon batches for AG brewing, and dont really need 3 primary fermenters, but the price seems so good (bear in mind glass carboys are much harder toget in the UK) and I could make bigger extract brews
I might get them,
what do y'all think of the price? Should I get them? I'm worried I might become an alcoholic if I start drinking 3 times as much beer. Also, they're only a 40 mile drive from where I am,
Thanks,
Chris

I think it would be a steal. You can always do partial mashes. Worst case, sell a few of them.
