Taulman do various nylon formulations - I've used Bridge which prints on glass with a dilute PVA coating ok. I'm quite impressed with the strength of this material.

You can also get an acrylic (t-glase) from them - have a look on http://taulman3d.com/

PLA is still a useful material even though it's not the toughest available - I've made a laptop stand from it and various bits for the kitchen - custom hooks for ikea cooking implement racks, plate racks for a cupboard, kitchen roll dispenser etc. Oh, and parts for the next 3d printer :-)
