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,

All the broken pumps I've seen were neglected and ruined on the pump side, not the motor. Not using a pump (letting it sit with old oil) seems to be the worst thing you can do to it.
