I have had the Plus, Pro, and Ultra's, they all work well, the Ultra obviously being more versatile. If you cant buy a cheap used one, check out AVtoolbox. Their products do a pretty good job. If you have about 5-6 hundred to spend, maybe opt for an old Lumagen vision, with its customizable resolutions, you can adjust resolution 2 lines at a time. It would also scale to higher resolutions, if, but probably when you upgrade. Let me know if you need a 25 pin cable to hook that up.
