I like Imperialstars a lot, probably the nicest lauan drums I've seen, although Yamaha made some killer ones too.
It's worth noting that there were 3 different versions of the Impstar shell, that is, disregarding the current version. The first were very thick and had equally thick rerings, making for a huge bearing edge that had a killer fat roundover. The next version still has rings proportional to the shell thickness, but both are much thinner. Not sure when the edge changed to a modern sharpie, but the final version is the same shell thickness, minus rerings.
