I'm just very skeptical, as I've already had to replace the evaporator on this car. That was fun... turned out there was a pinhole in one of the coil's u-bends.

Not necessarily. Just find someone that can pressurize the system (dry gas or refrigerant) and leak check with one or all three methods. If the ONLY leak is in the compressor or any of the hoses/fittings that will be removed with the Sanden retrofit, then you know what you have to do. If you find a leak somewhere else (condenser, evaporator, hose connection etc), then you also know what you have to do. If your leak is slow, then it is harder to find. If you have dye in the system, you can use the glasses and light to view the condensate drain (above trans). If there is a leak in the evaporator, you will see green in the condensate. This is the best way to check the evaporator. You can soap the connections around the TXV and hoses, and also the condenser. I usually have my A/C shop check for leaks before charging, but I have my own gas bottle (CO2) and hose assembly that I use to check for leaks. My bro' has an R4 system in his 300D that works for a couple months, and leaks out before the hot season is done. I have tried every method several times to find the leak, with no avail. Good luck to you with yours...Rich
