I have my R10 set up in my basement with a hitting mat, screen and projector. It's been awesome! I plan on doing a full golf sim at some point but for this winter I just went ultra budget.
R10 - 800$
Hitting Mat + Ball Feeder - 600$
Projector - 250$
E6 Connect - 400$ for 1 year.
I don't use the hometown hero app though, I sprung for E6 connect through my laptop and I've been very impressed.
Have you updated the R10? The last update seemed to really kick up the accuracy.
