There's apparently a G305 X coming out (54g?) the release date is unknown but it is out in China.
The MCHOSE G3 is supposedly a better alternative, but much like with all Chinese clones the software will be useable but poor, you'd probably just make your changes and never run it again anyway.
I would avoid Attackshark like the plague, by far the worst manufacturer of Chinese clones along with AJAZZ.
At the moment the industry it all over the place with loads of Chinese companies just cloning the popular mice, niche companies taking part in the ultralight weight war and major companies doing almost very little...
My main recommendations that should be within your budget:
Ninjutso Ten Air (one of the best internally designed mice on the market)
Scyrox V6 (40g, affordable and a great shape)
MCHOSE G3 (just a G305 clone)
OP1 (has flatter
Part of me would suggest getting a SUPERLIGHT 2c, as they fixed the dogshit mouse feet, but the M3 button is still faulty. If you can get it for cheap you could go for it though if you don't use the M3 button as much.
Also its worth checking out https://www.rtings.com/mouse/tools/3d-model-shape-compare? as a shape comparison tool.
The don't have all the shapes available (they seem to avoid clones which is understandable) but it allows you to actually get a better idea of the shape. ELOShapes is great to get numbers and a quick glance, but it's just outlines and you can't see the side angles.
