Need paypal premium member subscription plugin

Hello,

I have seen several plugins that provide a subscription service via paypal but I need one that does the following and is simple:

– Allows already registered users to subscribe as a premium member by clicking a button that directs them to paypal to pay.
– Allows me to hide content in pages from none subscribed members using shortcodes and display a message instead.
– Any other additional features would be great.

I would much appreciated any suggestions put forward on what I should use.

Many thanks,
Elliot Sowersby.
