Welcome to PCF!
Read a lot and see a lot before you spend.
"Ceramics" and "China Clays" are Fords and Toyotas (different forms of plastic, the former being more durable; still a lot superior to cheapo plastics with metal slugs inside them).
"Real American Clay" (with still some high-end plastic and metal in them) are either:
-No option Porsches (Off-the-shelf CPCs and Key West chips, also made by CPC)
-Customized Porsches (custom CPCs)
-Vintage Ferraris (second-hand Paulsons and TRKs, or BCCs).
The third case is well above the reach of middle class people. by now. Don't be carried away by fashions.
