Hi Irish, although you did not mention where in SA, Cape Town, George, Durban or Johburg, here's my two cent's
Firstly
www.delta200.co.za (think they got a baron 55 or 58 not sure,but i guess u would need to contact them for the twin
then
www.capeaeroclub.co.za (also baron)

These are all in Ape Town, hope this helps
