In my opinion, get the Etek3 if you want something with warranty, you'll get the chance to register it with planet eclipse and they will close enough garentee every part of the gun, unless if it's down to user error like trying to plough a field with one.
An Etek 3 is comparable to an ego08, it basically feels so similar! I've seen plenty of ego 09's sell for around the £350 mark if you wanted to save a bit of cash. They are by far superior then the 08 because of the solenoid.
Alternatively, there are plenty of other second hand high end markers out there for sale. Just make sure you get a chance to shoot one before you buy one
I know Yorkie has done a few noobie days to get more people involved, but at the moment the season has picked up and most weekends will have teams scrimming against each other which is no way a bad thing as you get a chance to watch and learn. Call mr.Yorkie and it will all become clear how to get yourself involved
