About scan converters again

[Janet Onopa <onopa@UHUNIX.UHCC.HAWAII.EDU>]

I followed with interest the discussion about scan converters that can turn a
computer signal to a video signal in order to project the computer monitor
image to a large screen, because we are considering getting one of these
devices.  Several people commented that these scan converters are not as
sharp as an LCD display panel, and are not very good for projecting small
type on a large screen.  Our local vendor is promoting a fancier scan
converter called a Scan-do that sells for $1495.  He says that the signal is
much sharper than a less expensive converter, and it is essentially
flicker-free.  It has very few manual adjustments that need to be made by the
us, whereas he said that the less expensive ones have several manual
adjustments that need to be ma.  Also, it can put out an RGB signal as well
as S-Video and composite, and can be used with both PCs and Macs.  One last
advantage--it can retain the image on the computer monitor at the same time
that the image is projected to the large screen (which not all scan
converters can do).  And it doesn't require either an internal card or
software that needs to be installed.
Has anyone used this Scan-do converter? What do you think? Does it improve
the image enough to be worth spending this much more?  Is the image good
enough to project small type that can be seen by a whole class?
Thanks for any help you can provide.
