Check Ain Khaled Gate Compound (At Ain Khaled area near Al Waab), I lived there for 2 years and it's very good, with lots of facilities (3 pools, gym, club house, supermarket, dry clean, restaurant/cafe, kids areas, tennis court.....etc) and apartments are available within your budget (http://www.regencygroupq.com/ain-khalid-gate.html) - availability is usually limited so hope you find one.

The compound belongs to "www.alasmakhrealestate.com" and they own lots of other compounds as well - you can check with them, they have lots of sales reps who can find you something. Best of Luck.
