I use a vista cruise on my 1300. You didn't say if you had an 1100 or 1300. The space for the universal vista cruise is very tight on the 1300, in fact it doesn't fit without modification. You have to grind down the unit a bit. I used a 2" grinding wheel in my drill and then it slid in just fine. Then you have to take off your grip (I used a thin screw driver and WD-40, others blow it off with pressurized air) for the locking mechanism and then cut off the end of your grip before you glue it back on. Really, quite an easy mod. I have a unique ability to turn 20 minute jobs into 3 hour ordeals and it went just fine for me. Because I'm an overly cautious engineer, I also got longer adjusting screws in place of the ones that came with it.
