ok...so where do i begin my research on components?   
 
who sells individual components?  and what's on the list?  motor, arm, platter & bearing, and switches...does that cover it? 
 
what are the main things i need to consider?  does my taste in music determine any components i should get other than the cart?  i listen to old jazz, dixieland and string band music...almost all older stuff.  and i would need 33 and 78 speeds.
