is a 5 lb co2 tank too little or should you go to a 10 lb for more money -- do you have to change the smaller out so often that painful etc even if running 2 5 gallon kegs?? Is a third regulator for gas remaining in tank worth the extra cash??
It costs nearly as much to have a 5lb cylinder filled as it does my 15lb cylinder.
Don't ask me why, the fool at gas place couldn't explain it either. Thats why I use the 15 for my kegerator, and I use the spare 5 for purging kegs for storage and cleaning.
