I know in another forum every trading report is about how people are scammed or recieve bad quality insects. This leads to a lot of animosity on all sides. Here, tell us who some dealers are that you have had good experiences with. I'll start it off.
Ebay sellers:
indowings - all "buy it nows", lepidopterans mostly from the Southeast Asia region, great quality, fair prices
ilo44 - many auctions, insects from all over the world, many interesting and rarely-seen insects
papilio1 - although some people have had issues with him in the past, and he does sell repaired specimens, I have personally met him and he is an honest, generous guy. He sells all his specimens in riker mounts
reisenpanama - I oredered a batch of insects very recently, and they look to be perfect quality. He even through in an extra Cethosia cydippe as a small gift.
Other sellers:
Butterflies and Things - a seller of dried insects, especially butterflies, based in Ohio. I would recommend them for any beginners, because they also sell supplies and offer good instructions on how to spread the insects. I had one quality issue once and it was resolved very efficiently.
Insect Collector's Shop (Collectionneur d'insectes) - good quality, nice specimens.
Hope others can expand this list, and help keep trading reports from becoming a battleground.
