LONCIN Lol dont do it.
Get a second hand brendon washer petrol or diesel . Be careful most are ex hire but saying that they have sat most of the time and are regularly serviced.
Brendon is just a name of a company who throw the parts together and slap their logo on it along with a ridiculous price.
Sorry I thought it said Lifan ffs I had just had a camera down and had a needle it must have still been affecting me lol. Lochin engines even thought they are chinese are ok but the only thing I buy chinese is special fried rice.
As for brendons they are very expensive but very reliable that's why hire firms have used them for years. The design is better than most I have used and they use the best parts around. Yes your right they just slap them all together and put their name on the machine just like nearly every other assembler out there from Wesley to jetmac systems.
The Op has around £800 to spend and IMHO would advise a used brendon for that price second hand because he is not going to get a top end machine for £800 brand new even if he asembles it himself and puts his own stickers on it with brand new parts. I said ex hire are usually serviced because they are.
All machines are just a frame ,engine ,gearbox,pump ,unloader valve, hose & gun with a name slapped on. You need to find who uses what pumps etc and then decide what suites you for what you will be doing.
