I'm a believer in second hand tanks, as long as you're careful to read the description properly and be prepared to replace some of the equipment if necessary.
My first tank was bought brand new and I don't regret that because it was a good gentle introduction to the world of fishes and all its paraphernalia complete with instruction manuals and no need for cleaning or wondering whether the filter is worn out or if it's really supposed to be running that slow...! However once I'd learned the ropes my next three tanks have all been bought second-hand, all for about a third of the RRP or less. All of them came with dodgy equipment but I don't mind purchasing new equipment so that I can kit the tanks out exactly how I want. The tanks and stands have all been in good condition and that's the important thing is that the tanks and stands have all been fine, no deep scratches, no water damage, obviously no leaks or cracks and any light fittings should be in good order with no rust.
I probably would not buy that particular tank though. I'd be looking out for a new-style Fluval Roma with the Fluval cabinet, but that's just my preference.
