What would be afair price for a refurb H77? Can anyone comment on the quallity of this projector? (please, don't tell me about H70, I know all I need to know about that projector LOL) Thanks!

I have a vaulted cieling room that was an addition on the house. 12' by 22'. The room entrance is a large arch at the front left of the room as looking at the viewing wall. Velvet curtains in burgundy cover this space. There are 2 closets on the viewing wall with an inset for a tv between them. There is a 10" horizontal top piece that runs the width of the room from which I hung my screen. The screen is a dalite model c (larger diameter for less wrinkles) and the material is HiPower (the narrow viewing angle high gain stuff). It is 58" high and 108" across making 119" diag plus masking. Viewing level center is about 5'. Lighting is controlled by custom fitted honeycomb blinds with mylar lining for 100% light blocking. These were purchased on sale for 1100 which included 3 full size windows and the 3 individual panels that make up a bay window. Due to some light leak with the shallow windows and the spacing of the curtains from the wall in the arched entryway. Daytime light in the southern facing room is just enough to read a newspaper or just below, depending on sunny or overcast. The room is near pitch at night with the curtains to the kitchen open. Private message me if you want my phone number and would like to come out and demo it, Ill fire up the arena scene from star wars 2 or something.
