I just looked at the Reo's- they're actually more reasonably priced than I thought they would be. I'm kind ofa skeptic when it comes to systems like this- for one thing, how do you regulate how much
juice you send to the atty?
It pretty much becomes second nature quickly. The easiest method is what is referred to as the "blind squonk" - you just press the bottle and draw on the atty or carto (without firing) until you hear a gurgle, or feel any resistance, and you're good to go. The REO's also come with a short piece of smaller-diameter "reducer" tubing that fits inside the main feed tube - this is best used with thinner juices to prevent over-feeding. I recently got a Mark Bugs Chalice rebuildable atomizer for bottom feeders, and it really works great with my REO Grand. Any excess
juice just runs back down the feed tube into the bottle, so it is almost impossible to flood.
