Very cool. Have you thought about filming a rocket launch? The smooth acceleration should cause very a interesting distortion.

How did you buy it? Can't find any shops online. Not on eBay either.

They only do business to business sales. You'd email them and then wire them some money (about $2000 in 2017) from your company.

What does that cost?

About $2000 I think, I bought it in 2017.
