My thing was to try and find complete, matching sets...hoo boy! My intention was to buy low and sell high. Every complete kit I got, I fell in love with ....and they are STILL in my drum room.
I played them all on kits. I love them. I would miss any of them when and IF I ever sell them....but the fact is that I now feel kinda responsible for making sure that the next person who gets them will treat them the same respectful way that I have...which makes it even more difficult.
So...be prepared to fall in love with drums in a whole, new way!
