Extra dimensions don't come cheap. If you've dreamed of a Sam Worthington-shaped avatar running through your living room, you know that 3-D projectors – the few that are available – have price tags in the $3,000-and-up range. (You also know that Avatar has yet to see a public 3-D Blu-ray release, but that's another story.)
Optoma's HD33 brings 1080p 3-D home for a 2-D price. At $1,500, it costs less than many 3-D-ready TVs, which, incidentally, can't produce images as large as 300 inches. That's 25 feet, in case you're math-challenged. Eat it, local Cineplex!
Actually, don't shred your concession-stand punch card just yet. Although the HD33 manages some impressive feats of 3-D magic, the reality is there's just not that much material to watch at home – yet. Most cable providers offer few, if any, 3-D channels, leaving you with a smattering of movies on Blu-ray – and neither Blockbuster nor Netflix rents 3-D versions. Again, yet.
Of course, movies like Despicable Me and IMAX Space Station are worth owning anyway. All you need is a 3-D-ready Blu-ray player, the HD33, and a nice big screen or wall. Oh, right, and glasses: Optoma sells its active-shutter specs for $100 per pair, though you can also use any DLP-Link glasses you might already own. Depending on the size of your family, you're looking at a sizable extra chunk of change for your minions to see those minions.
The painful irony is that the projector does come with an RF emitter that links to as many pairs of glasses as you can afford, and without the hassles of line-of-sight. Once the HD33 switches into 3-D mode, it takes no more than five to ten seconds for the glasses to sync up.
