What Outlets?

I serched through the threads and did some reading but most of the threads are very dated and the refrences are no longer accuriate. I need about 8 outlets so I am trying to stay in the $50 range per putlet but can go higher if needed, Anyhow I it down to :
1. Acme Audio Labs 20A
2. Hubbell 8300

My question is the the Hubbell 8300 and Acme I see them all over is there differences are some cryoed and some not?

Where is the best place to get these?
