disregard Midchucks advice :DMarcus makes some good ones. certainly worth a trip to Newport for, to try a couple out... you should be able to get a good well built one for around £35-£50 to start you off get two or three ciapans (beaters) in varying weights as well
I wouldn't bother with a tunable at the beginning stage, I've never used one myself and they could be a pile of trouble
