To be honest; I think your quote is 'reasonable'. If it is 500 for the whole job, that will be the new condenser, nitrogen flush, evacuate, fill with refrigerant & PAG and finally test.
Econ is always on as the compressor is disabled to protect it when there is no refrigerant and (more importantly) the possibility of less PAG oil in the system.
The pressure in the system is not too dissimilar to that in your tyres - and you can have a slow puncture detectable in a bowl of water that takes weeks for the tyre to go down.
They haven't really de-activated your system out of mallice - have they? You took your vehicle in and asked them to investigate why it wasn't working. It's fair to pay for their investigation. They have found a leak so it would be irresponsible to recharge with a gas that shouldn't really be released into the atmosphere into a known leaking system.
As above, if Econ is on all the time the compressor was not working to any degree; and it would be the outside air blowing on you making you feel cooler.
