I have a Tac Force I believe. It has a single shoulder strap, it can be configured for horizontal or vertical carry. I don't drag it around or stress it much but it does seem to be well made. Lots of velcro (high grade) and web attachment points on the inside. Seems like it was about a 120 $ with a few accessories.
The iShot is pretty universally touted as superior, more money than I wanted to spend though. The Pelican hard case is bombproof and very spendy, remove the foam and drop in the iShot for that I'm So Tactical look.
