First off I just want to thank @TankGuy for his ViewSonic donation offer.
I had a quick look at the above two links for the projectors in question.
One is the Sony VPL-FH31 and the other is ViewSonic PJ359w. FWIW This is not an exhaustive review and my opinion only.
Some quick comparisons:
Sony - 4300 Lumens
ViewSonic - 2,000 lumens
Sony Resolution - 1920x1200
ViewSonic Resolution - 1280 x 800
Sony Lamp Time - 3,000-4,000 hours
ViewSonic LampTIme - 2000-3000 hours
Lamp Replacement Cost
Sony $217 Cad Projector Lamps World link
ViewSonic $181 Cad Projector Lamps World link
Looking at the specs the Sony comes at a $300 purchase costs vs the donated (free) Viewsonic.
The Sony has a larger resolution and brighter (more than double) screen. It is quieter and has about 1000 hours more on the lamp life than the Viewsonic.
While I believe that free is always good I am a believer that in certain situations providing a better viewer/presenter experience can be beneficial and I believe in this case the Sony will provide a better viewing and quieter projector for presenters to talk.
So I am happy to donate $30 toward the purchase of the Sony.
If it is decided that we will take the Viewsonic then my thanks to TankGuy!
