Perhaps the MSR Missing Link?
An originally $200+ retail-priced shelter, fully enclosed for two (netting and floor), weighing about 3 pounds, and now being sold for about $100. Pitches with two hiking poles since no poles are included.
The Missing Link is described at MSR's website:
http://www.msrgear.com/tents/missinglink.asp
Recently, REI made the Missing Link available at a price below $100 (year end sale?). It is currently discounted elsewhere (might again find it near/below $100 somewhere as it appears to be on the trail to "discontinued").
For example, on sale for $124 at Moontrail per this link:
http://www.moontrail.com/msr_missinglink.php for the Link listed at about $125, plus more info and photos.
Be sure to click the "here" link at the Moontrail site to see the "additional photos" provided there.

"The ultralight shelter withstood a windy Rainier storm that dropped 5 inches of rain in 24 hours and proved so roomy and well ventilated that our 6'6" executive editor happily shared it with a 5'10" friend." – Backpacker Magazine 2005 Gear Guide

Haven't used the Missing Link myself, but it looks real interesting — unique, too — and it seems to offer a lot of shelter (at a lighter weight) for the discounted price.
