I've had an 82 614, an 84 410, and an 84 620. The 410 was the best, the 620 was Ok but had some issues (no fender clearance!), and I never did like the 614. In fact, I gave it away three times - once boxing it up and shipping it across the country - before it "stuck." It's only 5 or 6 blocks away now, so I'm not sure it's finished with me yet. Weird, huh?
But in general, they were very well regarded at the time - all the more so 'cause nobody famous was riding them.
