Yea, you can get the 6-spider diffs for $20-$22 each and the 8-spiders for $32-$39 each if you find the right guy selling them, and others are selling the 8-spiders for $65-$75 each. When you are looking for 6-spiders, just remember that any Hyper diffs will work, and I think a couple other ofna diffs (Lito "george16" knows for sure)...when you are looking for the 8-spiders, you can find them listed as either "spider diffs" or "torsen diffs".
