Yeah, I would agree. My guess is he is pretty darn busy still trying to get everything shipped out and responding to the emails as they come in, hence him not posting here directly to address concerns at this point.
All-in-all, we got a steal with the Kickstarter prices, and I'm glad I backed this project.
Just being honest though, looking at the retail prices today, if I were in the market for an insulated SS mash tun, I would be pretty hard pressed to choose the Chapman model over the SS Brewtech model, which is only $50 more. I'm essentially going to spend about $50 swapping out the dip tube contraption to something 1/2" end-to-end, so with the Kickstarter price I'm still doing alright, but at the retail price you'd be neck-to-neck with the SS Brewtech price.
The SS Brewtech comes with (what's perceived to be) a more accurate thermometer, drains to no loss, but does not include the recirc port that the Chapman model does. For my particular setup I wanted a recirc port, but if you don't need that, the SS Brewtech model seems to be the better piece of kit.
