If you are going to practice making stocks, I would suggest getting some good files and rasps, not machinery. If you are planning on going into the business, I would suggest buying a duplicator.
I am not sure where you are looking, I buy pre-carved stocks for lever actions all the time. Haven't seen any $1,000 lever action rifle stocks. Last one I bought was a XXX Fancy feather crotch blank for a 1886 and cost $375. Plain utility-grade walnut precarved semi-inletted stocks cost about $100 or so depending on the rifle. Most of the money is in the handwork to fit and finish the stocks. For the 1886 stock, I billed out about $1,000 in labor by the time it was finished and checkered.
