FWIW/IMHO, the major drum companies haven't 're-invented the wheel", in terms of shell materials&construction.EVERY drum company either uses birch or mahogany or a combination of maple/mahogany or in the case of Gretch/Ludwig it's maple/polar/maple.AND more then 90% use Keller shells!, with the exception of Ludwig&Sonor who have ALWAYS made there own shells!.HOW many different ways can you make a maple or other woods shell?, i.e. it's ALL BEEN DONE BEFORE!, number of plies(thin/thick), different type of lugs, different positioning of lugs.R.I.M.S systems (&variations of the R.I.M.S. system).IMHO i believe that shells have become thicker!, HOW can a drums shell project &resonnat if the number&amount of plies are CHOKING the sound?, AND THEN they(drum manufactuers) put THICK heads on i.e. Pinstripes! :(.I've also noticed 20ply snare drums! :(.Another thing is that more then 90% copy oneanother anyway look at early (&later Yamaha) hardware they copied Rogers!.Once again FWIW/IMHO.the ONLY companies that HAVE attempted&tried to 're-invent the wheel" as far as shells are concerned are the boutique/custom drum manufactuers, such as Brady, Sleishman(1ST EVER COMPANY TO MAKE&OFFER A FULLY -FLOATING SHELL DESIGN BEFORE PEARL but Pearl's snare is NOT completely &totally free-floating the name's a misnomer!), Capricorn,Spirit.THESE companies make&offer DIFFERENT TYPE of shells at least (as well as maple).With the exception of Ludwig ALL the other drum companies have gone back to making thicker shells&DON'T cater for the "vintage" drum collector/enthusiast (except DW who do).BUT WHY are DW &Brady(&other boutique/custom) drum makers far&way MORE expensive then the japanese&even Sonor who in the 80s were " The Rolls Royce of drums", especially in price! :(.They ALL buy there shells from Keller (except Brady&the other 'Aussie" drum companies) apart from session pros WHO can afford a DW top of the line or a "boutique/custom" kit these days?, especially here in Australia! :(.
Feel better how mate? hehehe.
Sonor stacks up like DW here. I would imagine there are trade arrangements with Oz and Europe that might make Sonor seem a little less expensive.
DW, Sonor SQ2, Gretsch USA etc etc are truly expensive however despite the quality nature of the product is still cheaper (in real terms) than it was in the 60's for our beloved vintage drums.
As for who can afford them. I went to the Monaco Grand Prix 2 weekends ago courtesy of Red Bull Racing (long story). Honestly, Neil Pearts entire DW kit could not buy you a table on a certain yatch for a post race dinner for you a 5 mates!!! Mumbling about a few hundred quid between makes falls into insignificance when a just a ticket to the bar cost €2000!!!! I got in on the guest list though!!! HAHAHAHA!
