not mine. a guy (SectionEht) in the blue room is selling a full PowerTank kit for $300.00. comes with scale and wrench too. he is located in the Bay Area. good deal!
Yes? That is the seller's claim and he also said he bought it "few years ago"; now the retail price may have changed... in fact, I think now that is the price you pay for a 20lb tank, but I am no expert of this product and I am a bit confused with all the options and different models.
add 1/2 tank or so of CO2: ~$8.00 and it is over $500.00.
to add a little perspective, there was a PowerTank group buy on the blue room two years ago...lowest price for 30 tanks came out to $400.00 not including the scale and wrench.
btw, there are cheaper solutions out there. i think Power Tank's got it going with their regulators as they do not freeze up as quickly. if i didn't already have one, i would be picking this one up myself.
