I just received a buffed 125B enclosure and i must say that i am very happy with the quality of the buffing.
There are a few areas where the surface doesn't look flat - almost like there were waves or something in the original casting, but they aren't really noticeable unless you are up close.
for the amount of effort it takes me to get an enclosure to this level of polishing, i'll gladly pay the extra few bucks to have them buffed for me!
