Don't scold me too bad if this isn't the right forum


....Anyway I am switching over to natural gas at my home and shop. I have the BTU's figured out but the brand I am not certain about. The tube heaters are probably the best to go with. And I am not in the market to spend a grand or two on on one unit. What if any of you are running these in your shop/garage and whats your take on the brands out there.
Thanks for any info.
