The RAF got rid because the airframes were at or near the limit of their fatigue index. Once they go above this fatigue index, they are not airworthy - at least in the CAA's opinion. The fatigue index is greatly affected by G, so if the aircraft isn't doesn't fly aerobatics, the fatigue index will hardly change, and an aicrafft that it near it's limit may remain flyable for a number of years.
The FAA allow the Bulldogs to fly in the Experimental category with no regard to the Fatigue Index, thus a number of Bulldogs have been exported to the US.
There are airworth examples for hire at Gloster and Coventry.
See what all your aeros did!
Next best thing might be a 150HP Pup. Not quite as aerobatic, but not quite as shagged out.
