That topper looks great Pete. You can take it apart and turn the lense upside down if u want if its like the ones I have here. Perspex window shld just slot in and out easily. You could mount it on the top of the machine instead of hanging it if u can invert the perspex lense.

I am starting to not like thinking about the AC/DC machine cauise I am over waiting for it to come.lol 

Its all good, it will be great when they come. First game wil be like taking panadol after having a bad headache.lol
