Recommendations for credit card machine at an event?

[Pingpong]

I've googled but I'm just wondering if anyone has any recommendations for a company that hires out credit card machines for events?
We have an online shop and currently just use paypal but are looking at attending a couple of events in the near future where a mobile credit card machine would allow us to take payment then and there.

From what I have heard they can be very expensive to hire. If you don't get many replies here it might be worth looking on ukbusinessforum as I know this topic has been discussed on there.
