Regrettably, I have to sell my SR3 Portable Plus. It was purchased in May 2013. Unfortunately, I was involved in a Road Traffic Collision in October that year, and as a result I since find it too difficult to manoeuvre around to the schools I was intending working with. Consequently, it has not had that much use in schools and is in excellent condition. Please feel welcome to contact me on 07581 441358 to discuss it and the price.
