Let's start with my personal favorite deal. For every 2 bottles you buy, you get the 3rd one free. That's an effective 33% discount. I love Anycubic Basic resin. It easily lets me print 100 34mm scaled miniatures at a cost of $40 per bottle. If you are one to throw around all your minis, this resin is not for you. its flexibility is non-existent, and its of average strength. BUT if you are looking for a lot of bang for your buck. This resin is perfect. Sturdy finish. High detail. Perfect resin for careful gamers.

I haven't tried Esun Resin myself yet. Big fan of their filaments. But I haven't had the pleasure of using their resins so far. That being said, I have seen enough videos to know that people generally feel that it is quality stuff. With a 30% discount that means you can now pick up a full liter of Esun Bio Blue for around $36
That's good value as far as I am concerned.

With only a 5% discount this resin comes down to $73 per liter.
That might sound a little bit rich for a bottle of resin. But as people who are experienced with resin printing are likely to know, not all ABS-like resins are created equal. This is a very tough resin. If you were to print a brick with it. You can easily throw it through a window. Not that I recommend that kind of behavior. But if you are looking for extreme toughness in your mini's and scenery this resin represents the move to make!.

Eco-friendly schmeko-friendly. Resin is still toxic goo from hell. Stating that something is eco-friendly because it's less damaging than another product is kind of a bitch-move. But hey, that's the cowboy-era of 3D printing for you. That being said. Excellent resin. Low Odor. EXTREMELY  high detail. If you want to get the most out of your 2K printer this is the way to go. This resin is totally wasted on people with a 480p screen. And it's also not 4k Resin. But for 2k,... this is probably as good as it's going to get. The price is... something else though. at $165 after discount... it's not a choice to make lightly. I can literally buy a pretty decent 3d printer for the price of one bottle. But hey. Maybe you are that one competition painter that hasn't realized they need a 4k Printer yet. Then this resin is right up your alley. I made the mistake of buying it once. The results were so spectacular that I didn't even whine about how much it hurt my hobby budget.

I'm not going to lie to you. If this was the Nova3D Novastan translucent clear resin... I wouldn't have even put it on our site. That's how crap that resin is based on my personal experience. But I can warmly recommend the Grey resin. It's a very good basic resin. Decent detail. Sturdy minis. Worth every cent you spend on it. With its $56 per bottle its a little bit steep for a "discounted" bottle. But if this is what is available in your geo, you will definitely not regret trying this washable resin.
