My way of thinking:
There are real bargains for new drum kits...
People buy less used drum gear (and the sellers have a hard time moving stuff). Back here, I see the same ads for the last 5 months - NOTHING is sold...
On the other hand - drums are still expensive... Sure You'll buy a set for cheap, but when You decide to have a pro set with cymbals, the price will reach $5000 in no time... And for half of that You can get a pro keyboard, a pro bass/guitar with amp etc...
Every pair of sticks is more than a guitar pick, every pack of heads is more than a set of strings...
Another thing that happened here - people use recorded rhythm... In order to have a duo/trio they don't bother with hiring a drummer. And 70% of the drummers back here use electronic drums.
The ones that use regular kits, can't make a gig that isn't under $800 for a five person band... The best we can get is $200...
