Hi , we kitted out with a professional set up two months ago and have not looked back since,,pull one to two jobs a week and we price well for this service, you won't go wrong with a Honda and if you're in it for the long haul buy the best kit you can afford, a Honda gx390 is my recommendation, i done a fair bit of research before I bought mine, speak to Damian at Qwashers as he comes highly recommended by a lot of the guys on the general cleaning section of this forum, hope this helps
