Great to hear Andrew Angell is able to sustain his work from a free model. That is the best model for everyone.

I am a little surprised by some of his negative remarks towards other PayPal integrations though. There's no doubt some of the official PayPal integrations with WooCommerce could use more work (as could many of the free ones - PayPal APIs are hard work). But some of the official extensions are also first class.

Most notably, the PayPal Express Checkout extension by SkyVerge is excellent. So excellent, Andrew himself felt some of it was good enough to copy into his own plugin (as discussed here: https://github.com/angelleye/paypal-woocommerce/issues/35).
