Brookstone iNeed Lumbar Massage Cushion - Yea... so I use this more of a foot massager, but for $60 bucks it is pretty versatile. You can massage your arm on this thing and even your hands if you are creative. As small as it is, its pretty strong enough to take a beating. Magic in a pillow and super portable.
Large Foot Roller - After a night of wearing heels and having a tight arch due to pronating, this little low-tech massager does the trick. The ridges on this thing actually feel really good. It's not expensive either. Body Back Company :: Home
