i would choose a machine from either Ashbys , Alltec ,or Airflex . The prochem machines are american sourced Edics , nothing coming from America matches the UK made machines for body quality , design , and 230v specific features ( like built in immersion heater )
2200 (+vat ?) will get you an OK machine feature wise ... another 500 or so and you get a top featured machine ... for eg An Enforcer with 6.6 vacs , 600psi ...and immersion . Or an Alltec evolution ... or an Airflex storm .
