I think your really should go with Mr. Nice Seeds. The reason the don't produce feminized seeds is because they're inherantly unstable and they don't make the best mother plants. MNS is run by the true kings of cannabis breeding, Neville and Shantibaba. These guys had a hand in breeding plants that are the foundation of breeding today. Plants like Skunk #1, Afghan#1 just to name a few. Neville was a breeder for the Super Sativa Seed Company, The Seed Bank (know as Sensi Seeds today) and was co-owner of Greenhouse Seeds in their glory days. Shanti's pedegree's I'm not so sure about but he is in the same league if not higher than Neville. With regular seed, you'll get a true keeper female and you can keep a male to make thousands of critical mass seeds if you like.
