Which R/O-D/I Filter?

[Buddyboy]

Hi Folks!!!

I think it's time to retire the AP Tap Water Purifier! Just wondering what everyone here suggests. It needs to be able to hook up to a kitchen faucet and provide enough water for a 50-75G tank. I was looking at maybe going through an online vendor such as PurelyH20 (or buying an Aquasafe through Ebay), but it would be nice to deal with a Canadian vendor. Any suggestions? Or is there a good filter that suits my needs that I can buy locally? Thanks very much for your help!!!
