The aeros endorsement that I did (a bit over a year ago) is probably typical of what you're after:
6 lessons, done in two stages. The first three lessons were:
UA recovery
Wing overs
Aileron rolls
Loops
Spins.
Then I got signed off on those and went out to practice them solo. The next three lessons were:
Barrell rolls
Snap rolls (not all a/c can do these)
Stall turns
Linking manoeuvres and making routines.
All up, around 6 hours dual.
There are several different aeros a/c, and they have different pro's and cons. Plenty of flying schools at MB do aeros endorsements, in the following aircraft:
C152
Decathalon
Victa Airtourer
(I'm sure there are more, such as Tiger moths down at Torquay, but that's a start).
Just like learning to fly, SHOP AROUND, listen to the pros and cons from each school and aircraft type, and the relevant costs.
Most of all, ENJOY!!! The most fun you'll ever have in an aircraft (below 5280 AMSL, anyway)
