I also got a refurbished PJ from Canada + JAC shipping fee and it cost me half of what is available here in PH.
Not all refurbished are defective, some are just returned by unsatisfied customers, some are display unit from stores, sa US ksi npakadali magsauli basta di nagustuhan ng customer.
Since manufacturer pala ang seller malamang repaired or restored na yan and they even give a warranty (although for US only and shows how confident they are with their item)
My refurb PJ works perfectly, no scratches or yellowing, even wrapped by protective film, in short...it looks like bnew.
It only had a trouble with lamp cover switch a few yrs. after but nagawa ko na din naman and everything else works fine.
And I think picture quality of a refurbished Benq W1070 is far better than bnew 32k LCD PJ.
And maybe it is worth the risk.
Re: screen, madai sa OLX na seller/distributor ng manual pulldown... some would even offer a delivery service.
Good luck with your refurb PJ!
