My opinion is that the Vitaloni Sebrings look the best, although they are probably not the the most effective vision-wise. The problem is that the sources Mike Drew shows for the Sebrings is that these are all plastic reproductions, and tend to break easily.
There was a vey nice set of NOS metal Sebrings on ebay recently, and I was trying to get them. I think the bidding got up to aound $600.00 for the set before I came to my senses and let the other bidder win. I made him pay dearly for them though.
