Other choices that you may want to look at:
1. Acura TSX SportWagon...21/30 mpg. On the highway, i hear people are getting 32-33 mpg. It does use Premium gas. On the plus side, you have one of the best stereo system avail, luxury interior (higher quality than Camry's), reliability/durability of an Accord, longer warranty, practicality of a wagon, memory seat, etc...all for the same price as the Camry Hybrid. In addition, oil changes in the Acura is dirt cheap...on par with Toyota's.
2. Subaru Forester...mini-SUV that gets 21/27 mpg on regular. Famous AWD system. Roomy, practical, etc.. Strong resale value. Price is around $27k loaded.
3. Ford Fusion/Lincoln twin. I looked at them a lot. Test scores are similar to Camry's, but maybe a tad worst (roof strength rating was not as good). Stereo not as good as Camry's (nor TSX). Mileage is same as Camry...Ford higher electric speed limit tricked the EPA in giving a higher city mileage. In addition, hybrid technology (as seen in Fusion) is not proven yet. There is also a potential defect with the Fusion's front subframe that i read about...not sure if it has been fixed by Ford.
4. Hyundai Sonata hybrid. This has the new Li-ion battery. Stylish (though i don't like it). The only thing for me is that the whole Hyundai line currently is too new...thus, unproven. But they do offer lots of features for the dollar!
5. Lastly, a Prius. I love mine. It is very roomy with tons of cargo space. And at $33k or so, you can get a loaded Prius Five with Advance Tech Package (ATP). I love ATP...it helps you relax on your highway travel. And, despite a 10 second 0-60, it is not underpowered...and i have no issues with merging on highways...due to instant power from hybrid powertrain. Crash test scores are spectacular. Fuel economy is as advertised (51/48 mpg; even better if you buy the lower end trim). JBL stereo is just as good as Camry's. Ride is better than Camry; but it is a tiny bit noisier. LED headlights are amazing at night.

5.5 If you still feel that Prius is too small (it really isn't!), then take a look at the upcoming Prius V (minivan version of Prius)...that gets 42 mpg. Link:
