The rapier II is a great machine, liner, shader, color packer at 350$ I do hear good things about the DK cranker like Sage mentioned. A production base model at 325$ sounds pretty good too. The swiss Machine is great for color packing and black shading National has them for 350$, Rotary Works are about 200$ I love mine for color work and black and gray, Treasure chest is a great color blending and gray wash machine at 375$ I think, one of the best color and black and gray machines in my opinion is the Centri but that is 600$ Also consider Slava he is a member here and he hand builds machines for 250 euro, and I am waiting on one myself they are seriously cool machines. he will also make them in different frame styles, but there is a wait time of about 6 weeks.
