I'm currently using Paypal (and 2checkout for hosting)

However for my main site I want to use a different primary payment processor with paypal as a secondary option (for those that want it).

Now who do you recommend. I've signed up for paysystems and played around with the control panel. Seems quite nice, what is everyone's current experience with them (rather than the archived stuff available via search).

They seem to charge much more than paypal for wire transfers. Are their cheque postings reliable?

If your asking in terms of payouts, yes. Usually we get the cheque 1.5 weeks after they show it as being paid, which is not too bad for Canada Post delivery.

We haven't had any major problems with them, support is always quick and very helpful. We don't use their actual shopping cart though, we built our own and interfaced it with their TPP-PRO setup.
