I checked the price and it seems very reasonable for a dedicated IP for trading. Pricing it this way also reflects the goodwill of the people behind the service, and it makes it easy for anyone to try it out and see if it fits their needs.
I was a bit wrong about the person.
He did not like me asking his client about how he secured his user/pwd and keys. Says he already answered that himself, apparently getting insecure about questioning a clients perspective on the offering. Makes me uneasy.
Not so ethical after all 
Guys, whats a good solution for Windows VPS for our purposes. Looking to buy asap.
