Suggestion on best gas high capicity chipper

[heromaker]

Hi, thanks to all who replied on my last thread. I'm in Ca and the new law is that you have to have a 2007 or newer diesel chipper to be legal. I am coming back after an injury and want to keep my overhead low. I have no desire to buy a 40k chipper, but I do want to buy a high capacity used unit. What is the best choice for a used high capacity gas chipper at least 12", I would prefer 15"-18".

Any suggestions?
