JohnDuncan:JoelSim:
heystak:What vinyl albums have you got?
Nada
What, really?!?! Don't bother then. Seriously.
I'll second that Joel - if you don't already have a decent vinyl collection then I can't really see the point. I believe that your CD player will equal most of the TTs mentioned, so you won't really be gaining anything.
If you wanted to explore the 2nd hand vinyl market (which I love doing), then get yourself a reasonable 2nd hand TT, (perhaps something like a Rega Planar 3, Linn Axis, Manticore Mantra or Systemdek IIX) from about 5-10 years ago - you can pick up these for £150-200 and will do the job fine for most used vinyl, and won't be disgraced by your system.
As already mentioned, you can then spend the rest of the cash on building up a decent vinyl collection...either new from places like whatrecords, or 2nd hand from fleabay or boot sales...
