Bluetooth speakers: What do you like? Models to avoid?

[decay]

looking at low-cost speakers, ran across this:

TekNMotion Air Capsule Portable Bluetooth Stereo Speaker

http://www.amazon.com/TekNmotion-TM-AIRC...B009EPSJWS

or maybe this

HMDX Audio HX-P230GY JAM Bluetooth Wireless Speaker

http://www.amazon.com/HMDX-HX-P230GY-Blu...007R6HUFI/

can't really swing a Jawbone for $150 ... any models you folks own or have heard that offer a good sound for the money?
