I have created a blog of a golf simulator garage setup.  It is an inexpensive approach to other sites and total cost including simulator is less than $700.  I have a 17” laptop.  One step and I can clearly see the results.  Most items are handmade or purchased from local retailers.  Casters provide easy setup and removal so truck can fit in garage.  It works for me.  Comments appreciated.
