(Warning - my second newbie post of the day.)

I've searched, but can't find anything like this... are there any sites
that compare teas from one company to another, for example, lapsang
souchong from Adagio compared to that from ROT, IPOT, Upton, etc.? I
realize it couldn't be complete, and teas aren't going to be exactly the
same, but does anything like this exist?

Thanks!
