Be patient with Midway, GW. I hit the "notify me" button for several brands of bricks and was able to go from half a brick to 6 or 7 bricks now and that's just since last May/June. Of course, like Lyon said, its been right-place/right-time and I had to drop EVERYTHING and get on line IMMEDIATELY. I had a few where, by the time I hit "submit order" they were out of stock. Having a sister-in-law working in a Walmart in El Paso, TX also helped! She found a guy who had 2 2-brick packs (4 total bricks) for $100. I owed her big time! You end up paying about $40/brick with the shipping (Haz fee sucks), but if you have them on backorder (and they're honoring it), they will get there.
If you lived closer, I'd hook you up with a brick. I bought a brick of steel-cased Russian .22LR for my daughter's Cricket and it won't extract after its been fired. I hate have to use pliers to get the spent case out. Only 5 rounds shot before I gave up. It may well feed fine in other rifles, but since it is for her and won't work in her rifle (worry about me later), I'm willing to part with it.
