I am probably quite a bit younger than some here so I did not grow up with 70's prog.
But I am heavily into modern Prog Rock and you would be suprised that almost all prog these days has very high production values, much more so than average music recorded today.
If you like stuff like Yes, ELP, Kansas e.t.c check out
Spocks Beard
Arena (ex Marillion members, brilliant)
Porcupine Tree
Ayreon
Enchant
and prog rock with a bit more harder edge
Dream Theater
Shadow Gallery
Symphony X
Pain Of Salvation
Threshold
