I would go with a Bobcat, then. When you're ready for a concentrator, either start out with a 5 LPM and then get another one later, or start out with a 10 LPM. I wouldn't mess with an 8 LPM unless you just wanted to for some reason. The extra 2 LPMs that a 10 LPM machine would have over an 8 LPM machine is worth it.
