Remember guys, besides those of us "spoiled brat Americans", that some of these people live in countries in which "vintage drums" don't hold the same reverence we give them, and they are looking at 5 kits as compared to 5,000. I do not agree with the types of mods being made, but we see literally 1,000 times as many vintage kits as some of these guys, and we pay far less than they do because we are....spoiled Americans...but we also made more drums than they did!
I'm living in Belgium Europe, just like Supraphonic D.
Vintage kits are indeed much rarer over here compared to the US.
Ludwig's pop up more often. (must be Ringo's contribution). Slingerland, Rogers and certainly Gretsh are rare finds. I would say that 90 to 95% of the vintage American drums are offered by collectors/dealers and very often are fresh imports from US, hence the high prices. To find them from first users is like winning the lottery and most of the time those people google the brand name and become convinced that they struck gold.
Price wise I would say that a good condition vintage American matching 3-piece drum-kit sells between 1250 and 1750 Euro. That's about 2000usd.
Personally, I keep my eyes open for nice deals from respected sellers and have my drums shipped from US,... cut the middlemen out sort of speak. Including shipping and import duties, you'd pay around 900 to 1200 Euro's, depending on year, model and finish of course.( The Euro/dollar conversion is still sweet)
Nonetheless, the Radio King posted above is way over the top, especially taken into consideration it's a re-wrap and has several kilo's of non original metal attached to it.
PS: some of the vintage drum dealers do offer quality stuff !
