I have also purchased from both companies, but Rich is my go to guy now on anything he carries.
I never had a complaint with Big Apple, but you can't beat the personalized service Rich provides. He takes care of his customers and is one of the few businesses that I recommend to anyone without hesitation. I've known Rich for quite a few years now and have gotten all kinds of stuff from him, cages, flexwatt, misting systems, rodent watering supplies, he is without a doubt one of the best suppliers out there and will definitely take care of you, not his staff, or other employees, he is personally involved with every transaction.
If he sells something I need, I buy it from him period.
