there is a variety based mainly on the size and type drum drum head tuning.
a small head with a non-tuneable can be as cheap as $ 20-40
high quality tuners mechanic or a mesh traditional hand woven rope style tuning tend to be around $ 150-300, but perhaps even more than that.

I do not know how low prices can be and also how they are made smaller. I would say a typical small is 12 "but can be smaller. A 12-Simi decent would cost about $ 350.00. But we can be of professional quality, ranging up to $ 800.00 or more. And Bigger rises away. You should be able to see the price musiciansfriend or ebay.
