They are $40+shipping new, so keep that in mind if you have one for sale. I can CC (if you are a dealer), PP (I am verified) or USPO MO for payment. My ACS will be here on 9/22/09 and I just realized I gave my extra tube to a buddy, so I need one ASAP. If you want to trade one for my Commercial sized tube, we can do that too. I will pay shipping on both to make up the difference.
