Butted mail is by far the cheapest, but the biggest headache, in my opinion. Some of the stuff on eBay comes from India, where some regular stores get it, but the shipping can be excessive since it isn't already imported in bulk. As Sir Wolf said, links are great for us to help give feedback. You won't find a hauberk and coif for $150, except *maybe* butted mail. But be prepared for weight, and replacing rings more often than with riveted.
