The A12 full kit will be $259, not including an op-amp. The easiest thing to do at this point is buy a discrete op-amp from Avedis (Brent Averill), John Hardy, or Millennia. The cheapest thing to do is use an IC op-amp mounted on a piece of perfboard.
The kits include schematics and a parts list, but no step-by-step instructions. The on-line instructions will be updated by the time the full kits ship.
