if u got on to www.smartpartseurope.co.uk and go to the shocker sports and accesories an i am either getting the virtical feed shocker or the shocker 4x4 powerfeed.
Have you tried getting a shocker second hand? You can get them really cheap at the moment. Would go for the vert feed coz a shocker has a monster rate of fire and vert will help you from breaking balls. Give london paintball supplies a ring. I think they have a shocker for sale for £400 or so London painball supplies.
