Stay away from these, especially the 333. They are prone to blow up the capacitors. This has been well documented on the internet. I had a 333 which had the caps replaced 3 times, once by the dealer before I bought it (per Madrigal's service log), and twice by me when I had it for 8 years. Per the tech at Madrigal at the time, it was due to the design as well as the caps themselves. They had later switched to a different cap supplier, but I am not sure if that ever did resolve the issue. You can't get these fixed by just any local tech either.
