I too used their "Conan" strain and have no complaints.
If you like the idea of more cells per package, you should also look into Imperial Organic Yeast and Omega Yeast. Imperial comes in cans with 200 B cells and Omega has 150 B cells in a pouch similar to Wyeast. MoreBeer carries Imperial at $10 per can and ritebrew.com sells Omega at $5.50 per package. I've used several strains from both of them and have been thoroughly impressed with both. Also, the owner of Omega typically replies to all customer service questions quickly.
