Credit card clearing houses, which is best, and what do I need to setup to use it?

[lugoismad]

Looks like I have a choice of several clearing house modules through OSc.

 

Which is the best to use for a small shop selling things with a median price of maybe 100$?

 

Its for a gun shop, selling parts and accessories online. Do any have any rules against that like Paypal?

 

And, what do I need to setup in order to use it?

 

It looks like the authorize.net module needs a few things like username, pass, and a few other things.

 

HOWEVER when you go to their website...I'm really confused about what to get. Could some please explain this as clearly as possible for me?

 

I would really appreciate it. Thank You.

 

Also, does that take care of the SSL stuff and everything too? Or, what do I need to go through to set that up too.

Is that what I need to set up?

 

One last edit:

 

Authorize.net's site doesn't discuss rates. What does something like this cost?
