Funding lags for indigent defense support services in Massachusetts?

I would like to know if other lawyers who represent indigent defendants have heard the same comments I have from my investigator and others about payment delays in indigent cases in Massachusetts.

My investigator has told me many times over the past couple of years about his bills for services in indigent cases going unpaid for months, and even longer in the case of services rendered at the end of a fiscal year.  CPCS pays for investigators, experts, and other necessary elements to a zealous defense from its own budget.  Those vendors submit their invoices directly to CPCS, and are are paid directly by CPCS.  The attorney appointed to represent the defendant certifies that the services were performed as represented on the invoice.  

Funding for the salaries of prosecutors and full-time public defenders has been a moderately popular subject in some media outlets here in Massachusetts lately.  Increasing the rates for private counsel who represent indigent defenders has been somewhat less frequently addressed.  I have heard nothing about the adequate funding of investigators and the myriad other vendors whose services are necessary to defend indigent people.
