I know what you mean. I currently have a projector system, but I need a traditional TV for the living room. The projector just doesn't work in that room very well. I had originally thought of a 65-73" TV, but for the price this is going for, I thought it was a good compromise. A 60" is still a good size TV and after thinking it through, it will actually fit in the space better.
Congrats on the projector! You are going to love the huge screen. Mine is set up with a 92" inch screen.
It's lots of fun to show off when friends come over.
