Stonecutters will likely follow the Riverside Oaks, Camden Lakeside, Horizons model and go through thre or four owners before it flourishes.
If Ashlar GC takes over, they'll need some serious membership $$$ to stay afloat, and I don't know how many people there are around Colebee/Riverstone/Rouse Hill and Blacktown who'll be able to pony up $3K a year.
Cumberland, which is the equal of Ashlar if not better is $915pa with no joining fee, there's Fox Hills just down the road and for those west of Colebee, Windsor and Riichmond are within 15 mins and less than $1000 a year (at last check, not much over $1K if they are).
It's a tough market.
