Probably get more for that K than you paid for the whole kit!
The Gretsch snare and Slingerland floor tom are cool and have value, but don't really belong
together. The ludwig/paiste cymbal has value as well, but the Rogers knock off stencil bass drum and rack tom have very little value, and are only interesting to see how well they copied 60's rogers hardware.
You don't really have a kit here, but you could part it out, keeping your favorite pieces, and buy a kit that you really want!;)
