no enforcer
Take your pick between the evolution and storm .
If i was configuring both i would choose the following ...
Evolution - i would ask them to fit the 6.6 vacs as they are working well /long lasting and cheap to replace these days .
I think 600psi is enough .
I would leave out the internal inline heaters asthey are only 2000w and add weight and add 400extra to cost . I would keep the in-tank immersion heater for sure ( works great ) . at some stage if you want get an external inline 3000w ( the powerflite heater from amteck uk is good value @ 500 )
The Storm ... i would pick 600psi , 6.6 vacs ... add the external magma heater ( you get 100 off it when ordered with a storm )
So My evolution , would be about 2500+vat ( or about 3000 if you buy external heater ) and storm ends up the same same about 3k .
If your just starting off and not doing large areas ... the smaller miniflex might be an good option also if you plan to bring the machine upstairs .
