I bought the 2000, liked it so much and bought the 4000 for micro adjustments. I have been shooting it since June.
Here is what I found. One, it is very quiet when shot. Just make sure its not contacting the riser. Also, NAP fixed the cable slide jumping problem it had earlier and now, super quiet on draw also. The rest is very accurate, and once setup properly, you will not have fletching contact at all.
As a hunting rest, its awesome. The included arrow holder that sticks fast to the shelf works great and with the outward pointing prongs, there are no worries of the arrow falling off, unless you shoot upside down.
I have been hunting with it for a week now, and so far, not a problem from it. Seems very solid and durable.
I highly recommend this rest.
