To be honest mate, the listing doesn't tell you too much about the projector, it doesn't even tell you the make.
1200 lumins sounds OK, but before I bought mine I read lots of reviews to make sure I was buying a good model. In the end I went for a panasonic, It's slime line which is important as I've got it ceiling mounted and had it for over 3 years now and it's been brilliant. The blacks are really black and the overall picure quality is excellent.
That one on eBay looks a little chunky, I'd go for something slimmer.
Here's a pic of mine....
