Did you have a price range? Both greenleafaquariums and ada offer very nice nano setups but the cost is between 150 to 300 depending on what all you get.
Other cheaper options can be had from Fluval but I've heard of CO2 dumps with those - i guess one question is do you have any fish in it to worry about (asking because I'm not sure what you mean by HC).
If you don't have any fish then end of cartridge issues wouldn't be a major concern. The Fluval setups can be had for closer to $50.
