Sad to say - if you have the 1.3 or 1.6 engines, there really aren't any - most after market gauge sets come with a fairly large sender that threads into a 1/4" NPT fitting, which is way larger than any of the ports near the thermostat housing, which is the optimum location for it.
If you locate it elsewhere it won't give you any indication until the thermostat opens, and if the thermostat fails shut, the engine will overheat before the gauge has moved from cold.
If you have a Tracker or Grand Vitara with a 2.0 or 2.5, those have the thermostat mounted away from the head and you could theoretically fabricate an adapter that will let you mount the sender in the line between the head and the thermostat.
