Using HUD

currently alpha testing HEM3 , not that impressed so far but i'm guessing its early in development . hud designer is pt4 hud designer , other parts are hem 2 .
came across another HUD today , hand2note which is free for 25nl and lower and 9$ mtts and lower.boasts positional hud stats and dynamic or static huds.downloaded it and looking at it now . doesn't look easy to set up but could be a lot more advanced than hem /pt

where do i get hm3? i tried looking for that before but i cant find where to get the beta
