If yearly fees for rollover IRAs are too high, find a different custodian. There shouldn't be any, particularly if you can add to it.
With this amount, you could roll it into a traditional IRA and then sully the rollover money by contributing your $2000 a year. You can also roll into a Roth after having it in a traditional IRA.
If you add even $1 of contributory money to a rollover, you lose the right to someday roll in into a new employer's 401k, 403b or other qualified plan. But since in an IRA you manage yourself, you have more choices, that isn't a big disadvantage.
If you have decent choices, to leave it where it is is a possibility.
If you roll it into an IRA and then start adding to it, the amount of the rollover does NOT count toward your $2000 annual allowed IRA contribution.
Best wishes, Chris
