See this at HD on clearance. Unfortunately the PP is not available at my local HD. Is the SL version any good? What base group? Good add pack? Is it worth $2.75 / quart? I have also seen this kicking around at a few other places I am sure it won't be long before the big discounts can be had. I searched for some info on this and was not able to come up with a whole lot. Thanks for the help.
