Heh heh yah we know you're a Zone fan alright 
Player1, for your info though, I believe the El Nino 2000 certainly
does not need a recon, it just has a couple of nicks on the
surface, that's all. And it's also a proactive ball, albeit not as
strong as the Shock Zone.
Player1 it's up to you, not here to force you to anything, just
given you other options rather than just the one you had. 
What you only need to do is to replug and redrill, plus the cost of
any inserts you may need. Which you would have to pay for the Shock
Zone anyway, just that the ball is $90 less. You mention the Zone's
plugging is already covered in the cost, though, that's a plus
point for you. Saves another $20-$25! 
$65 difference for a El Nino 2K replugged once and a unplugged
Shock Zone.
Tough choice indeed. Problem is you made a promise to him,
so...
anyway.. do let me know if you're keen.
