no probs, you wont regret it trust me, the amount you will use compared to myself and guy it will last you a long long time mate.
a few tips here to help you keep it in tip top condition,
"always" give the main tank and collection chamber a good rinse out and a clean after "every use", specialy the filter or it will start smelling manky and eventually rot.
dont over do it with the chemicals in your spray tank as this will limit the life of the pump so keep your dilutions high.for really manky seats/carpets etc use a strong mix in a spray bottle for spot cleaning etc.
be carefull with the spray head as they are expensive to replace.
