+1 on the Rox. It rocks! No really, it rocks. Rox rocks. I realize I sound like an idiot but I really mean it.
I had bought some months ago but held off on using it because I "wanted to finish the old stuff first." When I finally did I couldn't believe the difference, if I could have foreseen how much difference it would make over the previous stuff I would have just tossed the old stuff out without using it. And the old stuff was pretty pricey premium stuff too!
Rox for me from now on. Sounds like Kien's method of buying a ridiculous amount is the way to go. I bought two containers of 1/2 gallon size and I can see myself using that up fairly quickly..

LMK if you order some .. I might probably go in with you so we could save a wee bit on shipping. There are a couple things at BRS I've been eye'ing but I've been waiting to get a little less broke first.
