Well I ended up going with the taprite one from noble. It doesn't have the zink bonnet but I only plan to use it for co2 so it should work just fine. What does the zink bonnet do anyways? Other than its got a higher raiting for other gases.
I couldn't wait anyways I've got a carboy all cold crashed and ready for kegging. This was my best option if I wanted to have beer for Christmas.
FYI dont buy cheap equipment! I bought mine a few years ago from everwood for around $60.00. A little after a year it started acting up... POS!
From what I read that one was for commercial use but overkill for a home brew system. I only went with it because I happened to catch it on sale and had a gift card from OBK to use.
I couldn't agree more with the cheap gear. For anyone considering going to kegging, don't cheap out. I did and have been replacing parts ever since, not to mention the extra CO2 fills due to equipment failure. Buying quality gear will always save you in the long run, I wish I had when I made the move.
