We received a Edmunds catalog with lots of cool stuff in it.

I have always wanted to play with vacuum stuff when I was a kid
and I didn't get much of a chance so I figure now is my chance.

By the way I'd recommend a belt driven pump. These are generally much
better made than the direct drive pumps, and should you need a new motor
there are a wide variety of replacements available.

Best wishes,
