We use a viewsonic. It is tricky to setup, but works ok once you figure it out. 
It is not: plug and go. You would think they could 
make a machine that knows you have a vga cable plugged into the vga plug, but 
maybe not. If someone gives you one, ok, but if you 
have to buy, maybe someone else on the list has a better choice.

No one has mentioned the cost of the bulb and bulb life. That bulb can be a 
significant percentage of the cost of the machine. 
Several hundred dollars for one bulb.

Not sure it (1500/ 2000 lumens) would make as much difference as some
people are suggesting:

at my state of advanced rust I had to look up lumen (for those of us who
predate SI units it seems to be the light emitted per steradian by a
standard candle) -
now I'm pretty sure that the eye's response to light is more or less log
scale - so the fox to the rescue:
?(LOG(2000)-LOG(1500))/LOG(1500)*100  && 3.9337
so a *perceived* increase in light of only 4% -  add to this that the eye
adjusts to variations in light intensity...
