I've got an E[ from both Lassen and Jamie, and to be honest I really wanted to love Jamie's work... buti t fell short. I've got a set of Barbers from Jamie and some Walkers from Lassen.
My Barber set E[ has a slight bump to it so the coins don't sit flush with the other coins, its not a huge problem but when you are "shelling" out that kinda money you want perfection. I can understand that expanding a barber half dollar is insane but why offer a product if you can't make it good. My opinion with Jamie is he has got caught up doing the Dean's sets so much that making a normal E[ is too much work and he just half asses it.
My set from Lassen is fantastic, for and E[ the coin covers pretty much the whole coin and I can easily flash it in front of people without them ever knowing. (Can do it with the Barbers but its noticable if you hold too long)
I honestly would go with Lassen, I called him up when I was getting my Walkers and said "Hey I got a Schoolcraft coin and its blah... how does yours compare?" his response was "Mine are perfect."
