Are these any good? I remember when I was a kid my dad had an older one that sounded like a mortorcycle when he was running it. I have a chance to buy what looks like 3 older models on craigslist. Can I still get parts for these? I am currently using a 066 Magnum every once in a while but it such a pain to get started. When I do get it running it is awesome. I would be using these 3 MC's for around the house for small stuff like older pallets and for backups. I saw the ad on craigslist for $60. Is this a good deal? Thanks.
