Good point, [user]Phil000[/user], but I think you're graying the issue between High School and College. My high school had virtually nothing; my college had better equipment than Broadway at the time.
[user]Saunier[/user], I'd go for the Ion before a moving light package. Stop by the New Member Board and tell us more about what you have now. Since you're new, I'll repeat my mantra: "In most situations, buying moving lights rather than renting them makes very little sense economically." Look at the ROI.
For teaching purposes the $49 LED PARs and $200 Disco scanners work just as well as the $3400 (new) PixelPAR and the $7500 (used) VL3000Spot.
This is why schools should rent.
