As a very satisfied owner of a Schroeder Model 2, I can confidently say that it changes the landscape and makes listening to music a pure joy.
In fact, I would recommend that you spend on the table and arm, and leave the rest of the budget on the cart. There are many good recommendations for tables = scheu, teres, galibier, redpoint, VPI scoutmaster. For arms, there is only 1 I would consider, and the model 2 is THE bargain.
With one of these combinations, just get a decent cart like a DL103R or the Shelter 501 and spend the rest of software. You'll be more satisfied with the result.
PS: Frank has a brass mount top plate specially for the DL103R, its a fantastic match.
