JM22 has some of the best machining i've seen on a clone. I though my ithaka clone was high quality. You should see this thing. If you are not in a hurry, I will take some photos tonight with my slr. They are phenomenal!
The center pin is fully adjustable as well, so you can mount a myriad of tanks and drippers on there, and everything can flush mounts, since the pin can adjust.
*Edit*
I dropped mine while running so save the neighbours dog. The switch was damaged. I like this mod so much, that I'm buying another one!

The only down side for me with this mod is the soft spring at the switch. This is an easy fix by simply replacing the spring with something a little stronger.
Hi Crafty, may i ask where you picked up your JM22? i have been drooling over their website for a while now, i was just wondering if you ordered yours from the website or if you found someone closer to home to buy it from?
