The in store price is better than the .com price. Get it in store of you can get someone to help pick it up. The unit can be converted to NG but I would really recommend getting a dual or tri fuel generator. Conversions aren't the same as a unit built specifically to handle multiple types of fuel.
I would rather use it mainly with natural gas. this way I can keep it running when needed non stop.
any good models with natural gas capability you know off at an affordable price?
