My own DSLR Steadicam from parts bought at Home Depot.
Canon t2i, Bower 14mm wide, Azden Mic, Manfrotto Quick Release 577
Estimate cost with Manfrotto 577 is $60 without under $15
I use my own DIY Steadicams in all my Wedding gigs so this thing is legit! If your interested, check out my JMZ Films 2011 Wedding Reel and you'll see how amazing this thing truly works! vimeo.com/29966102
