I don't think your price point is realistic.
I'd get the 65" Panasonic Plasma (although I understand that some videophiles think that the upper-end models are noticeably and meaningfully "better" than the lower-end models).
OR
Get a 1080p projector and have as big a screen as you want.
Edit: also, don't completely discount the fan noise from either a projector or from a DLP-RPTV. My main display is a 61" JVC LCOS RPTV; it still has an excellent picture, but the fan noise is certainly audible.
