[Uc_mediatechs] I Need Input on Projector Selection

[Jeff Wagner]

Michael,

At UCSC, we haven't used any of the models you listed, but we do have 
experience with similar models by some of the same manufacturers.

We have 4 or 5 Sanyo PLC-XF31 (the XGA verson of the EF-31), which have 
been very good projectors.  Good image quality, rock solid reliability, 
dependable lamp life.

We've been using quite a few Sanyo PLC-XP41, XP46 and XP51 projectors, 
similar to the XP55 but without the DVI input.  These have good 
performance for the price.  Two cautions on these, however, which may 
keep us from buying more:

1.  They use an extremely fine air filter that's very effective at 
trapping dust, which keeps it out of the optics (good) but clogs up more 
quickly than a more conventional filter (bad).  We've found in dusty 
environments that we have to clean the filters as often as every 2 weeks 
or the projector overheats and shuts down.

2.  Switching between inputs takes 5-6 seconds, which is way too long. 
For some users, when they push a button and don't get an immediate 
response, they start hammering on buttons until something happens, which 
only complicates things further.

We have two Panasonic PT-D7500U projectors which gave us loads of 
trouble right out of the box.  These problems seem to be sorted out now, 
but it took a year and three expensive shipments back to Panasonic's 
repair facility in Kansas.  I know other folks have had great success 
with their Panasonic projectors, but our experience has not been very 
positive.

I'm hearing that Epson has dropped their educational prices on 
projectors, which is making us take another good look at them.
