You can try to use CAN paint first, as don't need to buy the equipment if u don't feel necessary in the future. Also when u use can then u will know the different nature of the different paint. When u have the first few experience then u will find the interest and then decided to buy the tools later. Also will not suggest to try Sazabi for ur first trial, is a bit difficult to make it good for no experience, better try HG grade Rx78 or those simple one first. Hope it's useful to u.
