Looking for X-ray Equipment Advice?

I am a chiropractor that has been working for approximately twelve years, and recently sold my business. I am planning to start a new one, and I am look­ing for new X-ray equipment. I take a majority of full spine films in my office, and do extremity work, as well. Hope this helps a little more. What would you recommend, new or used. And are there any affordable digital units out there. Thanks! Dr. Joe
