First thing I would tell them is to get it for themselves before they lapse on yours! It will make a difference on them getting it. It is easier if you are insured to get others than not being insured. That way they have at least the continuous coverage thing going for them that way.
I've been shopping around for some myself as mine is being done away with by the company. If they are healthy and young that is a big plus for them. With all the ones I've been checking into none is going to be cheap, but young will make a slight difference for them also.
Check with a State Farm insurance office, they offer Assurant which used to be called Fortis. It has been the most reasonable monthly price I have found over all the usuals, Blue Cross, Humana, United Helath Care ,etc.
Good luck to them and MOM (or DAD), PUSH them into getting on it right away!
