Clive, I got my Mk4 in Dec 09 and have not looked back. My previous gun was a Wally LG300 ( still have it), and though I dont want to compare, I must say that the EV is in no way inferior.
I have won all 7 FT competitions I have entered in since Dec but one when I had the flue.
The biggest improvement I must say is in the standing dept. I love the balance.
The support has also been great.
The basic accuracy is on par with the Wally.
Here by us the EV's are cheaper than the other raceguns so it makes perfect sence from that perspective aswell.
IMO you are bying a great gun if you go ahead with the purchase.
SCREW IT JUST DO IT.
