I'd suggest getting the Electric Eye DVD. It has some BBC performances from 1975 to 1980, all music videos from 1980 to 1990, and most importantly the Dallas '86 concert (aka Priest...Live VHS) in remastered form. If you're not too irritated by the Turbo-era songs and stage clothes, it's a nice concert to see.
If you're in for a more classic performance, get Live Vengeance '82. As the name suggests, it's from the time they peaked in America, and has a much different setlist to Dallas '86. It's currently the earliest full concert video that has been officially released.
Those two are the most essential ones for any Priest fan.
