Cartridge suggestions for SME Turntable


I just purchased a SME Model 15A w/309 tonearm.  What are some of the best cartridges that pairs well this amazing turntable, say under $5K. 
Thank you!

...  Not sure what this sort of spring rauliruegas mentions ...
He's referring to arms that allow dynamic balancing with a spring (such as SME V) rather than static balancing using a counterweight.

To be more clear, the spring mechanism is usually used to apply VTF after the counterweight is used to balance the arm. Some users employ a combination of the spring and the counterweight to achieve the desired VTF.
Thank you everyone for their suggestions. This is all been very helpful and I am learning a lot. Still a long way to go but I feel good about the process.

I also wanted to extend my gratitude to Mr. Colin King @gestalt. He has gone above and beyond in supporting me through the process.
Thank you cleeds for the interpretation. I mean that sincerely as Raul had me a bit lost. 
I have used a Schroder CB and have the chance to play with it a little.
Fabulous arm. My assessment of the SAT arm is based on the observation of it's design. If you look at a picture you will notice that the vertical bearing is high above the record surface and that you can not draw a line from the center of the balance weight through the bearing through the center of mass of the cartridge. The cartridge extends significantly below this line. This is a static balance arm. Because of these 2 traits the SAT arm can not track a warped record as well as the CB. If your records are not warped it does not matter. As far as the sonic performance of these arms? Do you really think that the SAT arm sounds $25,000 better? A tonearm should have no sound of it's own. Certainly the Schroder is going to sound better on a warped record. Less warp wow and cantilever deflection. On a flat record I would bet no one could tell the difference.
