Hi everyone, I'm soon to start roasting cocoa beans and from what I read through this forum it was suggested that a Unox combo oven would be the better option for roasting. I'm still debating what would be better, if a Unox combo oven or a modified coffee drum roaster. The options I am looking at are the following:

For drum roaster it would be a 6k Craftmaster: http://coffeeprodirect.com/roasters/coffee-drum-roaster-craftmaster/

For Combo Oven it would be a 10 full sheet pan Cheftable: https://usa.unox.com/en/cheftop_gn_2-1_2005pe

I was hoping to see if anyone that has had experience could enlighten me with pro's and con's with both machines.

Thanks ahead of time.
