Technics SL 1200 GR

Hi everyone,

I know that a lot of you might think I am crazy but it is what it is.  I heard a Rega Planar 6 play a few days ago and was totally mesmerized with the sound. This will be my first TT and I am the type that prefers to buy the best I can instead of starting small, selling and upgrading. I have to admit, I do enjoy fiddling with upgrades but the idea is to get a future proof turntable and upgrade stuff like cartridges, etc along the way.  

Before you recommend that I get the P6, its simply out of my budget. I could consider the P3 if you believe its better than the SL 1210 GR (not the latest model 2 but the original one). 

Anyway, here are some questions I was hoping you'd be able to help me with:

• What will a good starter Cartridge?
• Should I go for MM or MC? Is one more complicated to install than the other? prefer something simple as its my first time.  Also, I read stuff like LO and HO.. For what ts worth, I will be using my Marantz PM Ki Ruby's built in phono (I believe it can handle both MM and MC, I could be wrong).
• Anything else I should keep in mind?  Basic products for maintenance? 

Thanks in advance for your help. I appreciate it!
