Query: The best clippers, last forever - 40 years and still going

I have been through a couple of discount store clippers that wear out after a couple of years of use. Tired of worrying about something failing in the middle of a cut, I finally decided to invest in a quality Oster 76 clipper. I was about to pull the trigger on Amazon, but then realized that this may be the same model that my Mom used to terrorize me with (OK, cut my hair) when I was a kid. So I called her about her old clippers and an hour later she had dug them out of her closet and told me to come get them; they were an Oster model 76!I did a quick lube on it and fired it up. It's way noisier than anything else I've used recently, but the sound screams precision instrument. Yes it weighs a little more than the cheapies, but really not as heavy and bulky as some of the other reviews make it sound.So, buy this as an investment. Use it to terrorize your kid, who will eventually inherit the Oster and appreciate it.
