Vibration Packs

Interact Tremor Pack
Manufacturer: Interact
Price: $15 U.S., $20 Cdn

Interact's Tremor Pack is a cheaper version of the Jump Pack and does give more rumble than the Jump Pack. The Tremor Pack is endorsed by Sega. I'm not very sure about the quality of the Tremor Pack. Check with your retailer for more info.

Sega Jump Pack
Manufacturer: Sega
Price: $25 U.S., $37 Cdn

I'm not sure what happened to Sega's Jump Pack, last I heard, they pulled it off the shelf because it wasn't selling well. One of the reasons was the third-party rumble packs were cheaper and had more vibration. If you find one, you'll be lucky.

Mad Catz Force Pack
Manufacturer: Mad Catz
Price: $20 U.S., $30 Cdn

The Mad Catz's Force Pack is expeniser than the Tremor Pack, but cheaper than the Jump Pack. More or less the same thing as the Tremor Pack. The Force Pack is also endoresed by Sega. I'm not very sure about the quality of this product either. But Mad Catz is a very well known company, so I trust them as much as I trust Interact. Talk with a salesperson at your local retailer for more information on the Mad Catz Force Pack.
