which turntable to buy for $1500 best value ?

i have a rega p2 hooked up to an arcam fmj a18. i want to take a considerable jump with my tt. i am considering marantz 15s1 but wonder with the great cartridge it comes with, is that what i am basicly paying for or does the table belong in that price range. other possibilities are the concept, used p5, used scout [heard they were tricky to set up] or possibly a rp6 which would break me for a while.
