I'm a big fan of Technics Turntables, they are pretty much bulletproof. I've gotten most of mine for pretty cheap, price is a factor with them, my bang for the buck is awesome. I had to look up the SL-1400, it's looks like an obscure model without strobe markings on the turntable, or maybe they had them, there's a few different photos on the net.
For a young kid, Technics came out with these beautiful, simple turntables, even with the plastic they were much more elegant then the competition. Some of the Sl-1400s in my search don't have the strobe markings on the platter, this was like magic dust to us kids, watching our older brothers fine tune in the speed was like they were sending people through space. Maybe some of the photos are wrong, I can't tell without a true catalog photo.
If the price is right, it's a great starting point, you can always upgrade and sell it if you don't like it, people really like Technics and there will always be demand for them.
