The Sinclair tool looks like a high quality, precision instrument (as it should for $100+), but I don't see a primer feed. If it requires individual handling of primers, that would be a non-starter for me.
Has anyone used the new Lee Autoprime? It's supposed to have an unbreakable handle (a very weak point on the old model) and a large square primer reservoir to accommodate even the Federal packaging. It also allows the use of any primer brand, although I admit I never followed their warnings about avoiding certain primer brands.
