Hi - can anyone recommend a reasonably priced projector to show
videos/presentations w/my MacBook? Thanks, Leslie
hi leslie,
what rox said about adapters is spot on. i carry several mac adapters
in my bag. dvi2vga mainly for macbook and older powerbok. i only need
one, but i carry my old ones for friends just in case they need it.
i bought an NEC when i first got into vidoeblogging. not sure what
has changed since then. projectors must be getting smaller i imagine.
after browsing around the web for projectors, i got an NEC VT670 that
was rated as best classroom model at the time.
I got this from amazon in 2005 and still going strong for me:

here's some basic info. hope it is useful and applies to newer models:
features: there are fancier ones, but I am happy with what I got. it
handles 1080p. can project front (white screen) or rear/backwards
(nice for being able to walk in front of projected image) or upside
down (mount on ceiling). lamp meter shows #of hours remaining (carry
a spare anyway). multiple inputs: two video, vga, svhs/rca, audio in/
out. these are selectable, not composite (can't overlay inputs on this
model). zoom. remote. auto image align from when you have to project
at an angle (no trapezoids please!). carrying case.
cost about $1000. eventually lamps are the real cost. can be as high
as several hundred each. you can find good stuff for less or more.
lots out there. in the end, i figured teachers probably new what
worked best in general situations and harsh conditions at a reasonable
price :)
some tips:
if you like a model, check to see if a similar model exists that
outputs more lumans (e.g., it's brighter). this is especially useful
if you have to work in bright rooms (e.g., can't cover the windows
much).
most wished for feature: the ability to not have to be so far away to
make a big image. check the projection ratio. some projectors project
large from short distances. In a small room, it is difficult to
project a large image. would be great if one could have lens options
like cameras, but generally there is little choice in low to mid range
projects. specs will tell you image size to distance ratio. I need
to move back about
carry a VGA extender cable. often useful or necessary. same for
audio cable from mac to rca if you have audio in projector. extension
cord for power is good too. often the best spot for a projector is
nowhere near the power outlet.
works with video ipod! :) very cool
here is some info from NEC on basics. from marketing, but still might
be useful
