EXS 24 Logic Sampler Users Group

Hi,
I've heard the EXS is "the one to get". I haven't yet bought it and 
wonder if someone here with some patience would tell me how it 
integrates with LAW. It sounds as if it is a plugin like a DX plug or 
maybe a stand-alone prog?

Your opinions of it would be welcome. How easy is it to use with LAW? 
Does it compare with other software samplers?

Thanks - appreciated!
