I have read all of the posts below and have the following to add - I have or have had three animals that came through Bushmaster reptiles. All three have had parasites. One died after about 1 year, probably due to my lack of knowledge and prompt attention at the time. She had roundworms and a type of lungworm which was the ultimate cause of demise. This was about 5 years ago.
The other two are a pair of Meraukes. These both came directly from Bushmaster with Hook and Roundworms. Kamuran advised me this could be a possibility as difficult feeders are sometimes fed geckos to get them going. I went into the situation with full knowledge of this issue and was satisfied. I've been happy with the animals, but they have presented challenges. They seem to be more susceptible to URI and humidity issues.
I would be careful of posting that something is definitely one way and not the other. One of the posts below alludes that Bushmaster animals do not have parasites. My example shows that is not always true. I would suggest that if you purchase through them or another importer that you hope for the best and expect the worst, that way you won't be disappointed. In any event, make sure you have some knowledge of how to deal with parasites or have a good vet. All this being said, I've been happy dealing with Bushmaster and would consider going through them again, especially if I was looking for something specific.
