To Mechans, Karl does not have a mediocre table. IMO the tables he is considering purchasing are a small step up from his current modified rig. However the improvement in upgrading from an entry level HOMC to a LOMC (with proper step up) is a much larger difference. The OP can not buy a "costly high end cartridge" for $2500 nor improve his TT tone arm situation all that much for that same amount of money.
I do not disagree with your statement "you nead a really good table to get the best out of costly high end cartridge" but the 10x5, although very good for the price, is hardly a high end cartridge and IME will not deliver a lot better sound on a better TT set up than Karl currently has.
