We do have some changes coming. 
We are dropping the cast housing for a new CNC machined housing. They will be black anodized and laser engraved with our logo. The cost of that cast piece has risen to the point that I can make it billet for a few dollars more.
What we are doing is grabbing the 1st 20 off the line and sending them to folks to make sure everything works out well, and also for those impatient ones that can't wait another week or so for the black units. 
These early units will be neither anodized nor engraved and will be 5.00 less for their trouble, since I will want feedback.
As always, those that have bought our units in the past can upgrade to the new unit if they like them better. There is no "functional" difference. It's just a cosmetic change. It'll be for sale as an upgrade on the web soon. All new kits will go out with the new housing as soon as I get some feedback from the 1st 20.
