Strudeldog, Yes I bought mine from Ebay, and from that seller, two of them actually. One for me and one for my old man to play around with as well.
It's quite possible I have no idea what I'm doing or talking about, as this really is man vs. nature in it's simplest form. Plants are programmed to grow no matter what. One thing I do know, is all of this stuff has been done before so don't try to reinvent the wheel. The Medical Dope guys have more money to spend and experiment on the actual science of growing, cloning and harvesting so let them do it. I'm more than happy to jump on the "growing bandwagon" for my own needs after they have spent all the time, effort and money coming up with the next greatest thing.
The instructions that came with the clone machine say no humidity dome needed. Easy enough, as I'm sure the guy making these kits has enough experience behind using cloning machines to recommend that none are used. I'm sure he doesn't want his customers to fail, as that's a bad business model. I don't have a humidity dome on mine as I really don't think it's needed. A humidity dome will certainly prevent the cuttings from drying out, but will also provide a great home for mold. In addition, making the transfer from the cloning machine to a pot that much more of a challenge as the plants will have to be slowly acclimated to no humidity dome.
I'll take some photos of the cuttings in the clone machine and post them and people can decide for themselves on what direction to go.
