I've been very satisfied with the Timbocca brand from Amazon. Almost never even a single broken one. Overall consistency is very good. There is some variation, but I have not noticed it translate into any noticeable issues in the field. At $25.99 for 5000, it's the best value I've found. I looked at the picture that PGN uses to showcase theirs and I was not impressed. Lots of broken ones and several that were shaped like footballs.
