It all depends on what you want to do with it.

I think that the Minor on a 5 LPM concentrator is great for making soft glass beads. It isn't the hottest combination, but it works just fine for lots of people. If you want to work boro, you can work small boro on that set-up. Pipyr has a tutorial on working small boro on a 5 LPM concentrator. I think she used a Minor for that tutorial.

If you want to work larger or hotter (soft glass or boro), you can always add a second concentrator to your set-up on down the road. Just make sure that it matches the pressure output of the one you have for best results.

To get the most out of what you have now, the first thing to do is make sure that your concentrator and torch are in good working order. Make sure that the torch is cleaned and has no carbon build-up that could block any of the ports. Also, filter maintenance on your concentrator is important to keep it putting out good flow and purity. Flow and purity are more important for a hot flame than pressure is with a Minor.
