[AG-TECH] Single computer node and good projectors

[Michael Daw]

No bulb replacements?! Wow. Our Epsons require new bulbs about once a year.
Considering their expense (£300 / $500ish for each bulb), this is quite a
problem. Is it just the Epsons that need so many new bulbs or is it that we
just use them more than you...?
