If you mean roto toms, they come in many ..... ah ...... types. The original were chrome uppers and lowers. Made by Remo, they are the most desired. They come in 8, 10, 12, 14, 16, 18 inch sizes. I've paid over $150 for 16 and 18 inch models. I've bought and sold complete sets, 3 times. Well,10, 12, 14, 16, 18 inch .... anyways. I never got into the little one. Later models came with grey bottom rims, black bottom rims .... and clone models abound, now.
I have some for sale but you're probably better off buying new because sometimes the shipping in the USA is free......I live in Canada.
I'm selling mine for $250 ($200 if you want to buy them and pay for shipping).
I have a fairly new 6" and a 'vintage' (I guess haha) 8,10 and 12 complete with rail. I bought new Remo stand for them a few years ago. They're nice - easy to tune and make a great addition to a kit. I'm only selling mine because I don't 'jig' anymore and I have a lot of drums = time to sell some stuff.
Thank you all for the help! Its really appreciated. And ill try not to get my fingers caught in the roto toms. Oh and I only spelled it rotor because I thought that was what they are called. My mistake.
