The email issued mentioned earlier this week is now fixed! You may also have received previous emails that were meant to be sent over the last few days - apologies, this was a one time issue and shouldn't happen again!
I'm looking at a ZCO myself. Buy once cry once. The 420 looks good and I'm curious for anyone to chime in and tell me why they would or wouldn't spend the money on this compared to a NX8 2.5-20. Thanks!
