A common toilet is the Jabsco.

They are probably the most inexpensive, but on two different boats I've had problems with them after about a year, and the kits for repair are quite expensive.
On the Ballad I installed a Raritan PHII which has given excellent service for three years so far. Individual parts and seals are less expensive, but I've yet to need any.

On either unit the pump and handle can be easily switched to the opposite side.
That's my only experience with toilets
