I have a drummers world nesting kit hand built in NY.
It's this one below, but I also added a 12" rack tom for more options.

So 10X8", 12X8", 14X12" (toms), & 18X14" (bass drum). No snare is included.
I have hard shell cases for the drums. the 10" tom goes inside the 14" floor tom (protected with removable pads) which goes inside the 18" bass drum, so that all fits inside one 18" bass drum case. The 12" rack tom has it's own case and sits on top of the 18". It's a fantastic sounding kit which is great for gigs around town. I am the original owner, and I bought this kit new in 2000.
No hardware or cymbals included except the tom mount and floor tom legs.
I live in Nelson BC, but I will be in Kelowna/Vernon on Sept 20th if you are interested.
