I bought mine when they were larger (over 400 grams) specifically requested ones that don't spin. Got two that don't got one that does but only so slightly during feeding - it's not a big deal.
As long as you ask most breeders will be happy to tell you if they've noticed a spin to how much of a degree or not at all. The reputation of the breeder is not the issue - most spiders even if they don't spin will carry the gene and will likely pass it on to some of their offspring - it's just something that you have to accept if you are working with spiders. But if you just want one for a pet - I recommend buying an older one and just ask the breeder - you can find ones that have little to no spin.
