IMO you want to find one that you don't have to always buy filters for to replace it. You can buy cleaner to put in some to keep the calcium and lime from building up, I think that is cheaper than the filters. It's all about personal taste, and you have to keep them clean!!!! It's not as simple as just filling it with water when you need it. Not keeping them clean can lead to other troubles.
