vibrating alarm clock

I need a good old fashioned vibrating alarm clock, if something like that exists.

I am quite hearing impaired and am looking specifically for something that vibrates rather than makes a loud noises. I am having trouble finding something cost-affective...I do find it interesting how expensive vibrating alarm clocks are considering they are geared for the disabled, but c'est la vie. Another perk of having bad hearing.

I received an alarm clock several years ago through a program for disabled adults but it was a piece of shit and stopped displaying the time after 6 months. It also costs about ~35 dollars brand new.

Does anyone have suggestions?
