Has anyone had any experience with Student Loan Express and Right Rate? I am stuck at 8.25% after consolidating my student loans 10 years ago. Dept of Education are now offering rates at 3.37%! and I am not eligible because I have already consolidated my loans.

Right Rate says they can pay off my existing consolidated loan and re-finance my balance of $49K for 5.5%. Has anyone worked with this company before? Is there another alternative to try and lower my rate from 8.25%?
