The other grinder that we stock is the Glastar Diamond Star Grinder. It is their base model, without any extras. No power windows, or A/C, just a 3/4" bit. It is good for those doing stained glass on a limited budget or those who know that they just won't be using the grinder a whole lot. We can also special order the Glastar Allstar grinder, which comes with the 1" bit, but it is quite a bit more expensive than the Superstar II.
