There are plenty of providers advertising edging and are cheaper. However with the lower price you also have to give up quality and for sure enthusiasm Mia has. She's still my first choice but I've tried these 3, can't say it was an outstanding experience but you might like it better than I did
Mohan in the city - indy, indian, decent boobs, late 30s-early 40s
Helen at Relaxing Spa - asian, late 40s, knows some edging technics
Victoria - asian, indy, 30s, not bad at edging but have to tell it to her straight and don't expect any other fun or nudity.
Hope this helps
