Heidi has plenty of bad reviews here, do a search. The others are all pretty new and have no reviews, but someone on TERB said Gemini is an ex-stripper and provides the stripper experience (presumably expensive extras and bad attitude after declining).
Having said that, in the Mississauga area Seduction Airport is still the best bet for getting BBBJ for a reasonable price, if you see the right girls. Try Kristy, Demi, Sierra, Holly, November, Lily, or Alessandra.
