well i gave my suggestion on feeding the crickets, but if you have already made you mind up then why ask the question in the 1st place? You can nickel and dime yourself to death and most ppl do when they think they need to buy the big label food, thus complaining about the cost of feeder's. /shrug
I just told you the plain simple truth, best bet for cricket food is something that packs the vitamins/minerals that gutload the feeder daily. When I used crickets to feed my chameleons i would only use cricket crack, and considering that cost of my cheapest cham was around 500 i was looking for quality feeders to keep my investments healthy, thus research pointed to repashy for vitamins/calcium and cricket crack for feeding my crickets. Those orange cubes you buy from flukers... they are basically
hydrated water crystals with orange juice absorbed as well. I used to use diluted v8 juice to
hydrate my water crystals and provided macro nutrients not just water.
There are plenty of views and opinions out there on this matter, now you have to form your own and whats best for you, your wallet, and your pets. I choose to be selective of what I drop in my feeder colonies, ie greens mold very fast and feeders will drag them up into the egg crates and chance of mold crashing your feeder bin just went up when that happens.
