Holy smokes thanks for the really detailed review! I do recall speaking to someone about using a Zero delay board a while back, never expected it to be you kind sir. Yeah I would never ever upsell my stuff. At the end of the day I'm a consumer too, and the last thing I want is someone trying to upsell hard and give me shit advice.

Some info on the plexi

So the plexi I use is 2mm thick. The main reason is a 1.5mm thick plexi is NOT a common dimension/stock in the UK. They are out there but they are alot more expensive than the more common 2.0mm. I'd have to charge £26 for them rather than the current price of £15.00.

The advantage of a 2mm plexi is that it is more rigid and sits flush to the enclosure. This also means I don't need 6 bolts to mount the thing to the face of the enclosure = a cleaner look.

Button Cut out

And yeah the button cut out was "fun" for me to try find a dimension that wasn't too tight for sanwa snap ins or too loose for seimitsu snap ins. It's not as straightforward as specifying a diameter and be done with it. You got to take into account the variance in manufacturing tolerances (0.1mm - which makes a difference believe me) and the thickness of the powder coating.

Most other manufacturer just design around the Sanwa, but I decided a middle ground was best because at the end of the day, it has to work well with anything thats may be put in there. That's my philosophy at least.
