** MAJOR EDIT **
Refer to this link to see the cloner. I took the pics from here and moved:

Here's some pics of the cloner I made for about $45.00. You can buy everything nearly anywhere. This is a 30 site cloner, and so far I've got 13 of the 22 to spout loads of roots and then I've already transplanted and dealt with those 13. Before the bubble cloner, I couldn't clone for poo. I did the exact same method as I did before, with the bubble cloner. Method before was clone dome and Rapid Rooter's with Clonex Gel.
Method:
Get a low branch; Snip - Find leaf node; Slice flush - Below leaf node; 45° razor cut - Take razor and scrap around the lower portion - Dip in Clonex Gel - Pick a site.
I cut a 10 gal Rubbermaid tote with 30 holes the size of pipe insulation. I had cut "pucks" out of the pipe insulation.. 1/2 inch diameter inside hole, 2" outer (?) Then I use use air pump with 2 airstones (14" ones) and a little 10-30 gal heater to make sure temp of water doesn't drop. Do the method then find a site and just drop it in. The lower fan leaves will hold it in place. I filled with with about 6-7 gal of water. You want the water to just submerge the stems....but as long as you have a good bubble going from the airstones, you're good. I also use General Hydroponics Rapid Start rooting enhancer in my water. I PH my water to about 6.0 .... but there's LOADS of debate on that one.
The last pic shows some clones about 1 week after transplant into 1 gal pots.
I'm just putting this up here to show you my bubble cloner, and I just can not justify purchasing an expensive one for nearly no reason. I'm not commercial.
*EDIT*
I was sure that I had got pics with the root masses underneath, but alas.. it looks like I flubbed! The root masses were huge! Larger than golf balls and less than baseballs. Also, I'm sure some of you may have noticed, I forgot to "tip" my leaves on my clones... tipping is thought to help the clone throw roots and stop vegging. Also, it helps airation around the clones, and not have a fan flipping them around like crazy. I had wished I did it, but I got more than I needed to take anyways
