Shower Pan Replacement - which one?

I have a 2009 Damon Astoria and the shower pan is cracking. It's plastic, not fiberglass, and is cracking in more than one place. I have come to accept I need to have it replaced. Who makes a good one?

Details:

* Hexagonal, 32" (I think)
* 10" tall to top of lip
* Greenish-brown, I'd prefer to keep it the same or similar to match bathroom sink
* Looking for STRONG; prefer strong over matching color
* I'm a full-timer (if that makes a difference)

Ideas?

Thanks!
