To say the least, I don't imagine you being able to get a hold of one. I don't mean to sound like a sour puss (that was incredibly gay of me to say), but they're extremely rare and when they're up for sale, extremely expensive. To make a comparison, I'll use myself as an example.
Currently, I have about 5.3 million credits. If an Acclamator were to come up onto CPM and I wanted to purchase it, I would need to take a loan out or save up around 100 times what my current amount is. (NOTE: That is only a rough estimate, and I'm sure if it were an auction it would catch a far larger amount than what I guesstimated.)
So, yeah. Don't mean to be a buzzkill, but that's a lot of creds.
