Fotga recently opened up their product line to include a new S-450 Hand Held Stabilizer for under $150 dollars. Judging from what I can see in the photos, it's probably comparable to the size of a Glidecam HD2000, so you're looking at supporting cameras around 6-8 lbs max.

The new Fotga S-450 includes a top stage with fine tuning knobs (left / right / forward / back), and the baseplate includes a swing out set of legs to prevent the stabilizer from toppling over. A telescoping post means it can collapse to support small cameras, or telescope out for heavier setups.

The system can be broken down into several pieces for easy travel, and the handle accept a vest (not sure which type). For more information and additional photos, check out the Fotga S-450 Hand Held stabilizer via eBay (found here)
