200bar @ 15lpm will be ok for domestic work(till the power bug kicks in) , lookout for a genuine Honda gx with either a cat or interpump and gearbox and return to tank bypass. Then a whirlaway,vario lance,turbo lance,2x20m pressure hose,puddle sucker,buffer tank,brooms,shovel,wellies etc and then just like me a bigger van

It may be worth waiting till the cold weather comes as you might a full setup going cheap on eBay.
