You can actually use a solenoid relay, it uses what's sometimes called Bang-Bang control rather than a PID loop with PWM. It basically involves turning the heater fully on and switching it off as it approaches the target temperature, then switching it on as the temperature drops. It's a lot cruder and the temperature is less stable since the heater is either off or going full tilt, you can't turn it on just a little for fine adjustment. It is usable if you're on a tight budget like OP says they are, but they're also wanting to use profiled linear rails so that's sending some mixed messages.
