what pump expresso machine do I buy

My consumer pump expresso machine just went out.  The thermostat finally 
died,  I think.   I would like to find another good, cost effective
consumer 
pump expresso machine with instant steam or at least a model which can 
produce steam quickly for more than one cup at a time.

Can anyone direct me to a good consumer pump expresso machine which does
not 
cost an arm and a leg?

Thanks,
