If you do replace the pumps, VDO brand in-tank pumps have worked well for me in the past, and I generally use Bosch main pumps, which are effectively the genuine part. They're $100 or so.
In the past I've used Pro Parts Sweden pumps without any issues*, and I've also used Goss pumps (generic pumps you can buy off-the-shelf at SuperCheapAuto) as in-tank pumps and, again, never had any issues. Just make sure you replace the fuel filter and in-tank pickup filter at the same time so you don't immediately put crud into your fresh pumps.
* I mention this because PPS don't otherwise have the greatest reputation for quality
