I bought one of the $35 induction heaters from eBay.
Be aware that all you get is the circuit board and the copper coil. I spent another $150+ buying a power supply, a water pump, silicone hoses, proper clamps for the hoses, connectors for the inductor cables, a small radiator, fans, a motorcycle brake reservoir to use as a fill point, and some stuff I didn't *really* need - ammeter, voltmeter, water temp gauge, a high-temp laser thermometer to measure how hot the workpieces get, and a small crucible and tong kit to use for melting metals.
I was going to use an old computer case to package all the bits in, but I threw out all the junk in the storage room a while back, so I'm waiting until a freebie comes along.
