Mitch, My thoughts exactly, except that Dan doesn't just start slapping parts in and hope it comes out ok. I looked recently and didn't see anything on his website. Its my hope he will take on the task of evaluating the Hap-z1es, and offer an upgrade package. I would expect that is going to take several months. Such an offering might have a very large market. I'm going to continue to sit on my ModWright Sony 5400 ES until it is clear if he is going to offer something on the HAP-Z1ES.
