Should I get a sodastream?

A friend who homebrews has a huge CO2 tank where he modded his sodastream intake to fit it. Now he doesn't have to bother with those small CO2 tanks they stick you with. I've wanted to curb my soda consumption recently and his set-up is actually really cool. Any seltzer or sparkling water CHADS here with advice?
