I found the "Voodoo Tactical 36-inch MOLLE Soft Rifle Carrying Case"
for $52.95 at the US Patriot Store LINK: Weapons Cases | Blackhawk Rifle Cases | Pelican Gun Cases
This is a very versitile, high-quality case, and shipping is reasonable. After reading the almost unanimous great reviews on it, I decided to buy it. Apparently, there are two types of similar bags being sold at CheapasDirt.com. The reviews from the guys who got this bag are fantastic, the ones for a similar bag are horrid.
The only catch is that US Patriot only got it in Olive Drab. I really wanted it in Black, but this price is $25 cheaper than an other place on the web (and I've been looking for about 3 weeks).
I found a good review of the Voodoo Sniper Drag Bag and the Tactical bag mentioned above... LINK: http://www.borelliconsulting.com/evals/other/voodoobags.htm
