I own my own tank also, but use the same supplier (where I got this) because of their customer service and the fact that they're local.
When snowmagedon happened and our neighborhood was without power for 5 days, they made deliveries to us.
The last few fills its been the same supplier, but that's pretty recent. I hate to lock myself into one guy. Wish it wasn't through the supplier. Oh well.
