I've seen some 200ts around for silly money. I had 2 or 3 after my 020s so I feel I can speak with some authority on the subject. They were a good saw, not without faults(carbs mostly) and yes, early201s were poor ( remedied through an upgrade) But if you pay through the nose for an old 200 you're a mug. The 201 is a great saw, the 540 is a great saw. It's the most important tool in a climbers armoury, get a new saw if you possibly can.   Pointless retro nostalgia IMO.
