A nose gear only retract will only cost you about $20, plus another servo, but building a mount and setting up the retract is fairly complicated. I used a Tower/Great Planes belly mount mechanical retract with a retract servo and the stock pushrod for steering, and it took some heavy re-engineering of the structure in the front of the airplane. I'd suggest you fly the Long EZ a bit before you take on that task.
