I would trust anyone who is semi established in the hobby over some of the big names actually. Even with that said I have only seen 1 claim in my entire time browsing forums of someone that had to put the animal down and disappeared after getting put through the ringer of why he felt it was needed. About all he had to say was it couldn't eat and didn't explain farther or give the animals to someone with experience to see what they could do.
So 1 claim that didn't even hold up well, out of multi-thousand of spiders? I'd say your chances are pretty good.
