Ibanez has a great 3/4 guitar called the Daytripper. There's a Daytripper acoustic/electric model on the market, but it's not as nice as the acoustic version. I tried both the Baby Taylor and the Little Martin and they were nice, but the Ibanez Daytripper played beautifully and seemed to throw more sound than the others. And it cost less than $200. I did some online research before buying and reviewers were universal in their praise for it. Mine stays in tune, plays like a dream and sounds as good as a full-size guitar. My dreadnought used to be my primary guitar, but now I find myself playing the Daytripper every day.
Though the Daytripper isn't available in most music stores, since it has been discountinued, you can still find it on eBay. It's worth a look, since Ibanez makes fantastic instruments that are priced much lower than the prestige brands. Here's a link to the eBay listings:
