Yes, you may indeed be eligible for a 13. I suggest you contact a local attorney in your area. 13's can be filed 4 years after a chapter 7, and although they do require some payment, they can reduce the amount you owe to a very manageable level and eliminate interest as well. You can have up to 5 years to repay.
In a nutshell, the time frames between discharge eligibility are as follows:
8 years between 7s
2 years between 13s
4 years between a 7 and 13
6 years between a 13 and 7 (if under 70% plan)
The time is counted from filing to filing — not from first discharge to second filing.
You should seek the advice of an experienced BK Lawyer. He/She may tell you that you are judgment proof anyway and need not do anything at this time.

The time limit between chapter 7s is 8 years from the date of filing of the first one. This presumes you received a discharge in the first case. The time limit from a previous 7 with a discharge to a new 13 is 4 years from the date of filing the 7. Based on what you've said, you should be eligible to file a 13 at this point, assuming you have enough income to fund a partial repayment plan. You should consult a local, experienced bankruptcy attorney for more detailed information.
