definately consider a pmr.
just get a ul trigger and it will still be cheaper than the mini, its not much heavier, really easy to maintain. or use the money left over for a new trigger and an on/off, an on/off is something the mini has not got an option for and is considered a down side.
if your on a budget get the pmr - you dont have to upgrade immediately, then you have saved £50 more than you would have done buying the mini, spent more than you would have done buying the ion but have infinately got a better marker, the build quality, the stock board has semi, psp, millenuim and nxl full auto.
just get a pmr or mini. not an ion
