Turntable question


I need a turntable for my system and need some expert guidance from the forum.  I like the Technics SL1200GR or SL1200G, big price difference for a "starter" to add to my "modest" high end system (Marantz AV, Parasound amp, Focal Speakers).  Not sure which to choose but think the GR might be a better option. The TT's that keep coming up are the above Technics, Riga, VPI and a few others.  I have no experience in the vinyl realm but sincerely appreciate quality sound when I get into my system.  I also need advice regarding the type of cartridge, etc.  I am leaning to the Technics because I have read it is easy to set up, reliable, good sound quality and of high priority, ease of use for my wife.  She is very sharp but likes simplicity when she gets home from work.  Help!!  Thank you for any advice!

I have located a 1 year old SL1200GR for about $500-600.00 and in excellent condition.  I have looked at the used Linn, Thorens, Rega, VPI, Clearaudio but am gun shy about getting a used high end TT then possibly dropping a fair amount of funds to cure any problems I may encounter.  I am thinking to get started, a "reliable," "relatively" new Technics is a good place for me to jump in. I am still very tempted to get the SL1200G but it makes more sense for me to spend less, get a good cartridge (Hana SL or what about the Soundsmith or Otofon Black?) and see how my wife and I like the vinyl experience.  My front speakers are the FOCAL Electra Be, rears are ceiling mounted (unknown name), amp is Parasound Halo A51, Sub is a Velodyne 10", Marantz AV8802, has XLR inputs for the TT and my IT guy said I don't need the pre amp?  Wish I knew more about this audio world. 

Thanks to all of you for your responses.  Extremely helpful!  I will post a note when I have everything on line.

That sounds like a good deal for the SL1200GR. You don't "need" a preamp, but a decent preamp will provide a noticeable improvement over the Marantz.  I've owned the Marantz AV8801 and AV7704.  They sound better than a lot of AVPs, but a good dedicated preamp will sound a lot better. You don't need it now, just keep it in mind for a future upgrade. 
I missed out on the GR but just purchased the sl1200G.  Will have it delivered next week, then I will begin the hunt for a proper cartridge and possibly a phono stage.  Thanks for all your advice to date!
