I have a walkingspree inspire, comes with a wristband and a clip, about $40 if I remember correctly. I got it right after my Fitbit fell off my wrist, never to be seen again. I prefer the clip, and often I just leave it in my pocket. The band is like a normal watch band as opposed to the Fitbit's simple clasp, but when removing an isolation gown, I've lost the unit out of the band twice. That and the fact that I had to remove to scrub my wrists, just not a fan of the wristband.
While on vacation, I've submerged it in water, snorkeling for an hour before I realized. Not a problem. Durable, fairly accurate, inexpensive. The mobile interface sucks a bit, but it counts my steps, so I'm okay with it.
