hey there I am thinking about buying a cheaper turntable to play some of my old LPs. I am looking at the fowlowing choices Stanton STR8-80SK, Stanton STR8-30B, Technics SLBD20D. I have a limited budget at this time. I just want to make sure if I do get one of these cheaper turntables will they ruin my LPs. In the future I will be upgrading.
