Hello, has anyone used the cpm film tools sidewinder shoulder rig, specifically the basic kit? i'm looking for a simple but solid shoulder rig and this seems to fit my needs. at $700 its slightly more then i wanted to spend but i also don't want to regret purchasing something of lesser quality. i've been doing a lot of research but can't seem to find much feedback on this item so any info is greatly appreciated. suggestions for other comparable rigs are welcome as well, but i'm almost sure i won't consider anything over $700. thanks!
