The EOS is what the epiphany should have been, the eos has a lot of upgrades that make it worth the money, its lighter than the epiphany and ion and does feel nicer, you get the bolt out back and newer reg, plus the advantages you get from using the inserts in the fire chamber are very good. The ND shocker is a nice gun, good trigger and good milling. But remember, in order to get the extra milling, i believe they actually had to put extra metal on the gun and then mill into that, making it heavier, at least i thought it was, the NXT is lighter, but the SFT i have found to be the lightest. The ND shocker does come with all the ups though, q lock, freak barrel, trigger, custom milling and eye plates. If you have the cash then the shocker is a good gun, as is the EOS
