New Projection Screen is Great but Need a New Projector

Hi Everyone I need some help. I just purchased a new projection screen from www.grayhawkavs.com and it is fantastic. It makes my last screen VuTec look like a sheet of cardboard. My problem is with the new Gray screen material should I invest the money I saved from the Screen Purchase to buy a new projector to take advantage of the new high gain screen? Dose it matter the image is so great now i cant think that i can get any better. Please let me know.

Thanks
