Yes, I have ordered from Dubia roaches, from Aaron Pauling, and from Roach Guy, and I can say that Roach Guy currently definitely has the most agressive pricing (and the worst spelling, not that the lizards complain!). In addition, I have found that he is quick to respond to email questions. All three suppliers provide healthy roaches. It pays to email and ask about the percentage of roaches in each supplier's "Mixed" which are 1inch or larger. Failure to ask this might result in your choice of suppliers in sending you a Mixed batch which is mostly very small, when you could have selected another supplier which, at that particular time, might be able to provide a Mix of much larger roaches. For instance, Roach Guy is currently (7-8-09) providing about 50% as 1in/larger.
