David Hall's Cellerciser rebounder mini trampoline, $20

Exercide rebounders are incredibly popular nowadays, and several brands are quite expensive and sought-after. Besides the Needak rebounder found in another Gallery entry, one important brand you must know about is the Cellerciser.

Per the Cellerciser website:

Before you buy a mini trampoline rebounder, be sure you're getting a high quality exercise trampoline. Many rebounders employ weak steel springs or bungee cords, which can cause sinking and pronation of the feet and knees, which can in turn result in back problems. This is where the Cellerciser® rebounder mini-trampoline comes in. Take your fat-burning workouts and strengthening exercises to new levels with this fantastic product designed with triple-tiered™ carbon steel springs and all-steel construction, for a safe and durable exercise rebounder.

I go into more detail about these exercise rebounders in the entry on the Needak mini-trampoline, so I suggest you check it out. Just like the Needak, this Cellerciser fits into a category of merchandise I like to refer to as the deviants, so called because they deviate so far, pricewise, from anything that anyone but those 'in the know' would expect! Think about it - who the heck would ever expect one of these mini trampoline ecercise rebounders to cost anywhere near $300?  

This David Hall's Cellerciser mini-trampoline exerciser rebounder sold on eBay for $235.
