First of all there are many other better options than an eachine wizard x220, such as the x220s, emax hawk 5, and some furibee models (refer to uavfutures reviews.) But, if you are certain on buying a wizard, I would 100% recommend buying a new fpv camera such as a runcan swift. The stock cameras in both the wizard x220 and the x220s are terrible. Other than that, there is nothing else you will need to upgrade because if you do you may as well build your own, better quad. I hope I answered your question OK.
