They ought never to go bad, leaving you stranded on a cross country. Aircraft Spruce sells some suitable for your starter.

With low surge at turnon the mechanical relays are a better choice. In addition to the wasted energy turning into heat, solid state relays may "leak" power even when "off," allowing your battery to drain over time.
