I'd agree this is the only low cost option to increase light output.

Other than that you will need $500 (give or take) and some time on ebay for a used OEM set. You don't need to spend money on refurbishing them unless the donor car was in an accident.
Generally speaking aftermarket replicas have noticeably worse output, to the point of you being better off with your halogens.
