needing opinions...

I'm planning on putting a throttle body spacer on my 87. I was wondering if i could get some feedback as to whether or not these things are a good buy and what kind of increases i should expect.

Supposedly "up to 20 horsepower" (in this case).. worth 70 bucks?

Any random opinions would be helpful in making my decision.
