The Cheat I bought has an alu half plate and I absolutely love how it feels, it's just a shame I still haven't managed to flash the PCB so I can't actually use it. It's definitely waaaay flexier than both of the poly plated boards I have. Seems like the OTD PCB is particularly thin as well which I guess is a significant factor.
One day I'll get this thing up and running properly. It really is super nice feeling.
If you have an Atmel ISP you should be able to flash it I think. I used an Atmel ICE 2 for my mini, but there are lots of alternative models.
It's my impression that a bunch of the later OTD boards have very similar firmware, but I'm not sure about the Cheat. Might be the case, if you need hexes. The 456GT, DGE, Corsa, and maybe some of the others all share firmware I believe and I wouldn't be surprised if the Cheat was also compatible, but idk what controller it uses.
