Mining CKB & Antminer K5

Hi all. Very new to mining but loving the detail in the Voskcoin videos. I’m hoping to start mining some CKB and looked into an Antminer K5. Can anyone tell me if this is a good entry machine to purchase for mining CKB? I see threads with details of around 2k coins mined per day but these are 12 months old. Do those figures still hold relevance? Are there any CKB mining resources out there to help?
