I've used three resins so far,
1: Anycubic Basic Grey - worked really well, great results but very strong odour, very strong, as soon as I walked in the room it was - woah! Smelly resin! $35.00AU per litre from eBay (on special, normally $50.00AU).
2: eSun Standard Resin - also worked well, great results and hardly any odour, I couldn't smell the resin when the printer was running. $59.99AU per litre from a local shop.
3: eSun eResin-PLA - worked just as well as the other two, with a very slightly stronger odour than the eSun Standard. $59.99AU per litre from same local shop.
My verdict is the eSun is the go-to resin despite the price difference because of the massive difference in the odour, the Anycubic was quite off-putting and almost made me rethink my purchase of the resin printer.
