If you need to buy a phono section in addition to the analog rig, you'll need to consider at least $100 for that.
I think a Planar 2 with a lower cost Goldring cartridge and a Parasound or Sumiko phono stage, could be gotten for under $500 for all of it.
This would just barely be getting you into a decent quality rig, and would not really be representative of what vinyl can be, but would be a good start. The tonearm would be the best part of the rig, and could be modded to take you quite a ways up the scale, moved on to a higher table. Everything else could be considered expendable when you upgrade.
