Some things I've tried lately:
SodaStream Dynamo LX: Got this for $60 on Black Friday. I love the thing. I've gone all-in with soda's, teas, lemonade, energy drinks, etc.

Bose Soundlink Mini: This thing is tiny, and for its size, sounds very good. However, it's not good enough for my living room. It lacks dynamic range and the sound is "flat." I returned it.

Sonos Play 1 speaker with free wireless bridge: The Play 1 is their cheapest speaker but it sounds great. It kicks the Boses' ass. My only complaint is that you can't use Google's All Access music service with it, which is where I play most of my music from. It would be perfect for me if it had that. Hopefully they will add it soon.
