Bobby,
I switched from Paycom to Jettis for my (very small) paysite, because they offer a solution for EU webmasters.
Jettis has an excellent support (and sales) staff, and seems to tread carefully, which I consider to be a good thing for a processor. So far their system seems reliable with decent throughput, although it seems a bit slow.
I have some small problems because I do not have a standard membership site setup, and their system is not flexible enough to smoothly integrate with my site. This won't be a problem at all for most people though.
Based on the month that I have been with them, I can definitely recommend Jettis.
I can't tell you much about Verotel, other than the fact that I don't know anyone who I trust that uses them.. (which is already enough reason for me not to use them either, I am not an adventurous type

).
Greetings,
Art
