I owned one of these projectors (upgraded to a ~$5k JVC) and can first hand confirm the quality for your dollar. Great all rounder for movies and sport. Great for gaming too.
Full disclosure - I personally know the reason for these refurbs is batches of the initial production models were supplied with lamp batches with flickering issues on eco mode. No issue with the projector itself. Epson accepted returns for all affected models instead of replacing/supplying a new lamp to customers. I accepted a lamp replacement for mine and enjoyed a year and a half of movies before giving to a family member and upgrading. From all reports the lamp issue hasn't resurfaced.
