There are so many digital projectors out there it is difficult to determine which ones will work best for art use without actually seeing them in action.
With just a quick look, it seems like the Artograph series are perhaps a bit over priced for what you get. A 3200 lumen
projector can be had for under $300. That is over 20 times brighter
vs a 150 lumen Artograph unit. The nifty grids, color to black and white, etc look cool on the Artograph, but you can replicate most of them easily in Photoshop in real time just like on the Artograph.
Unless the tricks included with the Artograph are a must have or you can't figure out how to duplicate them in software such as Photoshop, I would suggest you compare the features and see what you can get in a regular non "art" projector that will be brighter and cost you less money.
- Closest Focus Distance
- Keystone and other perspective correction adjustments
- Light intensity adjustment
- Remote Functions
- Ability to read from memory cards / sticks, etc.
- "Short Throw" focus (Some won't focus at smaller sizes, make sure that the smallest image size it can project will meet your needs. Some cheap projectors won't go less than about 30 inches.)
- Tripod Mount (pretty important to line things up with your canvas.)
