Things to consider:
1) Lumens (more is better)
2) Resolution (XGA is good enough, you probably don't need HD)
3) Mean life and cost of replacement bulb (a biggie, and there is a wide variation in both - some bulbs are rated at 200 hours or less. If you use it two hours at a time, that's only a hundred uses - replacement bulbs can easily cost half of what you paid for the entire unit)
4) Depending on whether or not you'll be toting it around, you may or may not want to pay extra for a more portable unit.
