Thanks to those that suggested getting Kontakt/Komplete
Finally got a chance to do some serious play with the Komplete products and, unlike Eastwest's Play, they Just Work(tm). They don't give me any crap, don't seem to crash, don't sometimes screw up bounces, and so on. They seem to do their job, without complaint or theatrics. Also I quite like Massive, which I didn't expect, I bought it for the sampled instruments, not the synths, but Massive is quite good.
Now I think I'll need to sniff around and find a good orchestral sample set for it.
