lol hoss.. Ya pistone there are 2 major companies here that I deal with. One being praxair. I don't know how big the tank was for 1500/month lease. Right now I usually only take 1 tank at a time and they only deliver once a week so I have to swap it in myself (45min drive) which is one of the main reasons I wanted a micro bulk or small bulk. How long will a bulk go without bleeding off? And on the liquids here, you don't need a contract but they are usually 225/tank plus $1 a day rent. I got them beat down on the price and had to take a year lease at $100 so I wouldn't have the $1 a day. And the company I use right now doesnt even have a local place to fill.. they ship them 2 hrs away. If I had a bulk could I fill as well?
