No Markham or North York narrows down your choices a bit.. Is Mississauga okay for you? Mimi@ASB (asbvip.com) and NN@Wetland (wetlandvip.com) are both very good spinners imo. Mimi has great service while NN I find a bit more attractive and great value at $160/HH. Age-wise, I'd put both of them in the MILF category but have bodies that rival many of the younger gals.
If Downtown, I'd probably give iCandy4u a shot like someone said above and try to catch Kerry.
