Hello I'm in the process of putting together the family home theater room, and more than year ago, I bought and Optoma HD23 projector. But since the HT room was still under development, I stored it, thinking that it will take some weeks or couple of months, but it turn into 1 year. So, 1 year...

Can anyone tell me anything about this projector? Is it for sale yet? How does it differ from the HD20? I would appreciate any feedback. Thanks
