I have the Etha and it works very well for me. It does everything that I needed it to do. IT is quieter compared to the Etek but there are very little A/M mods available for the Etha compared to the Etek. Both are solid guns and you wouldn't go wrong with either one. Look at it this way. If you buy the Etha you will have money left over for a barrel kit, tank, hopper, mask or PAINT. If you buy the Etek you won't have the extra money.
Never argue with an Idiot. They will drag you down to their level and beat you with Experience!
It's not the WILL to WIN, but rather the WILL to PREPARE to WIN that will make the difference!
In-Hoc Signo Vinces!
