Your biggest investment will be a reliable thermostat which will be around $100 to $150, you will also need some heat tape which is pretty cheap and for the rest it can be anything from a cooler, an old fridge, or something build out of PVC sheets.

I spent about $150 for my incubator which holds 27 clutches. Basically my cost was the thermostat and the heat tape, the fridge was free.
