PISTONS DO IN FACT WEAR OUT!!!! along with the cylinder. Piston can be sealing fine and be close to out of spec. They wear on the front and back of the skirt and the cylinder gets out of round.

~$300 for a set of pistons. Try vertex as they make many of the OEM pistons.
Used complete running motors

Now granted, you could probably get away with using that used piston...If you are going to do that and half ass it just buy some ebay used pistons($20) and slap it together and sell it. If it is your commuter do it right and have the good feeling it is tight and done correct and you will not have problems down the road. But complete running engine on ebay...$300-$400 plus shipping.

Now the important question is...why did you lose coolant? fix that first before anything. Water pump, hose, head gasket...
