I want a couple also but I'm broke.
Ive learned that my time is valuable. While its is cheaper up front to buy a used part, the time and money spent to look and work as a new part is not worth the time and effort. In the long run your better off fronting the money and buying new. done deal. And less headache.
If I have ever learned anything from my current job, its what is stated above. Some people see buying new things as throwing money around. In the long run its actually more efficient.
