SD, I say the new water proof zippers work. I got new rain gear 2 years ago because my old Cabela's stuff was very heavy 4#. It had served me well for 15 years, I maintained it, but was ready for a new set. The stuff I got was pretty pricey so not what you're looking for. I've seen where the surface DWR treatment can be reactivated by a hot drier. All rain gear needs to be maintained after awhile. Check out this video and don't be afraid to follow it.

I do use a cheaper Marmot Precip set around the cabin and like them. They're cheaper, packable, but no water proof zippers.
