Well if you ever decide to do it:
Get as large a container as possible, the larger the better but try to stay under 2 feet deep. I used a 20 gallon Rubbermaid container.
Cut out the depression in the lid and line it with metal window screen, do not use foberglass, they will eat through it.
Get some egg crates from the market with your eggs. Make sure they are clean as possible. If you can find the large ones they are better, stand them up so you have almost the entire container full of them. On one end, stack them up the right way for strength or put in a stronger shelf type structure. this is where you willl feed them, give them water and collect their eggs.
To give them water, use those water gems that they use for plants. They expand and are great for giving them a water source without getting anything wet. Feed them greens, apples, carrots, cukes, zukes and a lot of other things as well as grain, baby cereal, oatmeal and many other things. I think I fed them pretty much everything including dog food.

One key, keep it dry! Any collected moisture can and will cause mold and will kill them all. I don't know why but any mold is deadly to them.
The egg tray should be filled with peat moss or coconut coir fiber. The coir fiber works great, is sterile and pH neutral. I actualy used plays and my first time and it worked great.

Take the egg trays and cover them with metal window screen to keep the adults from eating the eggs. Every week, take it out and put in another smaller container with some sort of dry bedding in the bottom. the baby crickets are TINY when they hatch. I used corn cob bedding from the pet store. Don;t mess with the cob until the babies are large nough to make sure oyu don't smash them accidentaly.

I will try to find the exact way I did it and provide more detail. I raised about 15,000 of the them from 200 in a year or so.
