I am happy with all the products at Catholic Productions. Great content for laity and clerics alike. I wish I had more time to intellectually-digest them all. Still, when there is a big sale, I buy as much as I possibly can. (I'll be honest, I haven't gotten to the WOD Conference 2009 yet, but looking at the speakers, I'm sure it's great.)
I'll add, while arguably anything would be good for the on-going formation of priests, the Sunday Mass Readings Explained subscription is especially good. Perhaps offer your pastor/priest a gift card as the content here is very digestible and can aid them with preaching, as well as be a tool to enrich their prayers life ... which truly helps everyone in the end.
