Projectors I have experience with include:

EIKI (we use this one in all the large lecture rooms) very easy to open
and change the bulb, includes a bulb changer and good optics - quiet fan,
and easy to understand controls (including the bulb changer - not hidden
under the front like the Elmo). Built like a tank. I'll get the model
number as soon as the classes change if you like.

Elmo HP-L355 (prefer the version with a bulb changer - I think that's
the one Ron mentioned) - a real workhorse and durable over time -
fairly easy to maintain.

Elmo HP-11 is OK for small light use applications, but has
no bulb changer and a switch that feels like it was made by
a toy company. We recently purchased a couple of these to use
in lab rooms for short/small presentations. Projector and cart
price (together) was only $199.

You might ask Peter back at KSU about the 3M projectors purchased
there in about '93 or '94. I recall them as being pretty good for
the price.
