In all honesty, I don't really care for crickets myself! Other staple foods you can offer:
Silkworms
Roaches (lobster, orange head, hisser nymphs)
Supplemental prey items that you should try as well:
Superworms
Mealworms
Waxworms
Houseflies
Mantids
Notice I'm differentiating between supplemental and staple prey items.
Even if you do not free yourself entirely of crickets, you can still provide a good mix of staple prey items (crix, silkies, roaches).
All of the prey items I mentioned are fairly easy to obtain via E-mail. Check local laws before ordering any, as agriculture restrictions vary from state to state.
