I suspect that the fact that you're asking this question is simply because you want a new toy. If you really wanted to get into vinyl, you wouldn't be asking "if" you should get a turntable, you'd be asking WHICH one you should get in a given price range.
That said, vinyl is one heck of a toy...if you enjoy a hunt-and-discover type of shopping, there's nothing like vinyl. Everything from hardware, to cleaning materials, to used vinyl, to new vinyl...it's all fun to buy due to its scarcity. Every time I find what I want, be it online, in a store or at a flea market, there's a little victory dance going on in my head. And when I bring home new records, there's nothing like cleaning and spinning a new find for the first time.
Good luck with your decision, keep us in the loop...
