I have recently purchased a EC120 after looking at both EC120, 505, and even considered a AS350. A friend of mine flies a 505, and is a nice modern machine, however I would say that in all my research I found that REALLY nice EC120's are selling for about 2/3 the price of pre-owned 505s. In my research I also found a pretty reasonable availability of spares mostly impacted by freight/shipping due to Covid.
