In my opinion, if you want to do that type of work with boro, you will want a two stage torch. The Bethlehem Bravo($800) is amazing and works great for this. I am selling a lightly used bobcat because I want to make pendants and marbles and small sculptures without it taking 45-60 minutes to make things no bigger than an 1" (solid).
That is so exciting to try a different glass! Boro is wonderful, but so slow in a small flame when trying to make a gather. Unless you have an 8lpm oxycon for a bobcat, I wouldn't bother getting a different torch until you can afford one that won't frustrate you within a month working boro. (I have my suspicions that a bobcat on tanked oxygen would be a completely different animal;p )
