If you go with the Epson 1080 UB Pro from AV Science (the AVS store) you can pay an extra $100 to have it quality controlled by one of their lead installers before they send them out.
He's recently been rejecting a pretty high percentage of them due to worse than acceptable convergence. To me, having this review and being guaranteed to get a top-notch unit is worth the extra $100.
For a total of $200, you get the review above as well as professional calibration. Also not bad considering you could never get a real pro to come into your home for this. (this may be overkill for some, but regardless what you think of the calibration, the first hundred bucks seems like a great investment).
