I've seen them both actually. The 1/6th was all rusted when I seen it last year. The 1/8th looks much better but faster than some go-karts lol. Better question is do you really want to pay HL $5-8k for a tank? I have yet to see a replacement part too. The guy told me last year he was only like the 2nd or 3rd to purchase one, I wouldn't think they would be big sellers from HL.
