I have used and abused my Steadicam Merlin Vest over the years, and although the ISO Arm has lasted me this long, the actual worn vest has slowly been degrading. I love the Steadicam Merlin Vest, and highly recommend the performance it gives, but even at $1500 dollars for the vest only (seen here) this is considered the low end of Steadicam's Stabilizer Vests. There are other more professional Steadicam vests, but obviously much more expensive. While I continued patch-work on my Steadicam system, I took the time to test a few other vests on the market.
Plastic Chest Plate Cracked on my Steadicam Merlin Vest
Build quality on the few aftermarket Stabilizer Vests i've tried over the years were good, in fact many of the worn vests I thought to be more comfortable and better designed than the Steadicam Merlin Vest. The only problem was that each ISO arm on the vests seemed to require a decent amount of weight to work smoothly. The springs were basically 'too strong' to fly your basic Glidecam HD4000 and DSLR Camera. In order to work properly the stabilizer should float in the air and the ISO arm should be very flexible and responsive to movement.
Current Stabilizer Vest Collection
For this new vest that i've purchased, the dual arms can be dialed down to fly an average DSLR lightweight setup, or dialed to support a heavier payload. The ISO arm is responsive, reduces movement that would normally transfer to the stabilizer, and allows the stabilizer to just float. I'm not a fan of a few aesthetic pieces such as the bright blue locking knobs and metal chest plate, but overall the build quality on the vest is good, lightweight, and comfortable.
The length can be quickly adjusted with a simple pull-pin, something the Steadicam Merlin vest does not offer. The Dual ISO arm can be repositioned on the left/right side, or removed completely very very easily. To attempt this with the Steadicam Vest requires more time and more effort. The buckles allow you to get in and out without having to lose your personal fitting.

I purchased this Dual ISO Arm Stabilizer Vest with the brand logo Wieldy, but has since undergone various name changes. The common one found (at time of writing) is under the brand 'CAME' (terrible name). If you're planning to use this vest under a Glidecam or Flycam, the post diameter is just a bit small. You would need to find a way to increase the diameter a bit for a snug fit with the Glidecam or Flycam handle.

At about $600-$700 dollars this vest is still not considered 'cheap or affordable', but in terms of the performance versus a $1500 dollar Steadicam Merlin Vest (seen here), it's a highly recommended alternative that i'm very pleased with. This dual arm vest is also found bundled with a Wieldy DV Pro Carbon Fiber stabilizer, which is a great combination for DSLR Video. You can find this Dual Arm Vest + Stabilizer via eBay (click here)
Video Camera Steadycam Dual Arm Stabilizer Load Vest
The vest is very helpful for longer video shots, but is not required. You can always purchase the vest at a later time and just start with the Wieldy Carbon Fiber hand held stabilizer. I have additional information and sample video footage shot with a Wieldy (found here). So if you are just looking for the Hand Held stabilizer, that can be found via eBay (Click Here).
