Well did some more research and put a pencil to some figures, looks like i'll just be going back in with a traditional gas water heater.

My gas bill is around $30 bucks a month, consumer reports says despite the claims in the real world the tankless heaters only save 20% at best. That's only $72 bucks a year. A tankless gas water heater sized for my whole house usage is $900 and would cost me another $150 more to change my vent. So, that would be an increased cost of $600 or 8 and a half years just to break even. And that doesn't include the yearly maintenance tankless heaters require. Just doesn't seem worth it when the advantage is you don't run out of hot water (if sized correctly) and I've never had my shower go cold yet anyway.
