The Epson 3100/3700 or the newer 3200/3800 are defiantly the king of low cost projectors with very flexible placement ability. They do have a longer throw then the BenQ but other wise can be shelf mounted anywhere between 10% of screen height above or below the screen or anywhere in-between inverted or right side up. Horizontal shift is also available although it will limit vertical to some degree.
EDIT: as far a PQ between them they are very similar and both in the same class. LCD of course will look different then DLP but both have their plusses and minuses. Epson has inexpensive lamps, is brighter for less then ideal rooms and guarantied no RBE. DLP is great for 3D, much better pixel fill and very fast video imaging for motion handling.
