OK. I am totally fed up with the company I ordered my CO2 equipment from two weeks ago. I ordered on 4/22, they said the ship date would be 4/27, last night (5/2) I ask where it is and today they tell me, "well, we just found out that one of the components isn't available anymore and, well, we could ship you the system with a different one then get you the right one when it is available. . ." I told them to have in enroute tomorrow or cancel the order. Assuming that it will not be shipped by then, what would you suggest in the under $150 category - and the vendor has to be reliable.
