My requirements were that my enclosure had to be able to roll up easily because my golf simulator space will double as my exercise room. My setup so far is:

The Sportscreen 16 ft manual crank roller, cut down to 13 ft, with a 13 x 10 ft preferred impact screen from The Indoor Golf shop ($329 plus $449)
The Sportscreen 10 ft manual crank screen and roller for side screen ($259 minus $29 with discount coupon)
The Sportscreen 16 ft bracket assembly to mount all on walls and ceiling ($170).

So a complete roll away enclosure for $1200 that rolls up in less than 5 minutes (You can buy motorized versions of the 16 ft and 10 ft for an extra $250 each).
