inputs...
if you could try and test it to hear its sound, do so...
look at the lugs, hoops.. are the lugs coated plastic or are they metal? tom mounting system -- are they isolated or do they go through the shell.. hoops...
finishes -- do they have the finishes/looks that you like
aftersales support... parts availability...
these are some of the things normally forgotten to consider in buying stuff... which could play an important role in the life of the product...
personally, i would probably go with the mapex qr since it has lots of choices for the finish (i like the angel wing), it has isolated tom mounts and i know i have someone to go to during problems and i would say it definitely has good aftersales...
but then again, this is something personal.. these are just some of the things i consider...
