Paypal Pro Recurring Payments vs Spreedly

I'm working on a recurring payments system for a client and was planning on using Paypal Pro Reference Transactions - however it appears that PP won't allow my client to use them (although I've used them before with similar sized clients).

So looking at the alternatives there are Paypal Recurring Payments, which cost an extra amount per month, or Spreedly, which costs a fixed amount plus a percentage.

If I go with Spreedly (which looks *much* simpler to implement) do I also need to pay PP for the recurring payments service? Or is the point of your service that you can handle all that stuff without us having to give a load extra to PP?

Thanks
