Can anyone point me to the most objective place (or provide information) to compare Unique, ERA or SPF? I "thought" I had settled on buying a new or used Superformance, but, was "educated" earlier that I should seroiusly consider Unique or ERA. Are these the three to consider or should I add or delete from the list. I know about Superformance but nothing about Unique or ERA?

I seriously have "Cobra" fever and seem to go one step forward and then take two steps back. For those that have been in my shoes....objective information or "direction" is appreicated!

Thanks in advance!
