My best advice is to find a local company that does just water borne finishes. Target Coatings is my choice. They are about an hour a 15 min from me, so I can run up there if need be.
Waterborne finishes have made leaps and bounds over the past few years and keep getting better. Polycrylic is a very old formulation. I don't bother with it. The only waterborne coating I use that isn't from Target is Rustoleum Ultimate Poly. Stuff is real good for an inexpensive but fairly durable finish. I use it on clear finished trim, railings, doors, etc.
