Want a really big TV? Forget LCDs and plasmas -- get yourself a wall.

Just last night, while watching the incomparable "Planet Earth" on Blu-ray, I thought: "This is pretty nice at 55 inches, but it really deserves to be 10 feet."

Hence today's deal. For a limited time, BuyDig has the refurbished Optoma HD20 1080p projector for $649.99 shipped when you apply coupon code BGTaxRefund15. That's tied with the lowest price I've seen.

The HD20 delivers full 1,920 by 1,080-pixel resolution and has a contrast ratio of 4,000:1. It can muster 1,700 ANSI lumens of brightness (meaning you'll need a reasonably dark room for maximum enjoyment) and can project on screens as large as 300 inches (that's 25 feet to you and me).

With two available HDMI inputs, you can connect, say, your cable box and your Blu-ray player. Need more inputs? You can always toss in an inexpensive HDMI switch.

I haven't found many professional reviews of the HD20, but over at Amazon, nearly 200 buyers rated the HD20 4.4 stars on average. It's obviously a very popular model.

Of course, because it's refurbished, you get only a 90-day warranty. Cause for concern? Perhaps, but usually with projectors it's the bulb you need to worry about. Replacing the HD20's will cost you around $140 -- crazy-expensive, but not at all unusual. You should be able to get a couple years from the supplied bulb, if my projector experience is any indication.

Although $650 is a pretty hefty chunk of change, I think this projector is a steal at this price. If you've never experienced the joy that is wall-size HD, here's your chance.

Bonus deal: Hard drive prices continue to dip closer to where they were last year. Proof positive: Buy.com has the Fantom GreenDrive Pro 2TB eSATA/USB hard drive for $99.99 shipped. These uber-popular drives come with a two-year warranty.

Bonus deal No. 2: Got an iOS device? Then do yourself a favor and download Smash Cops, which is free today only. It's a crazy-fun police-chase racing game that rewards you for going all demolition-derby on the bad guys.
