Novak 231 rebuild kit

Has anyone bought one of there rebuild kits? There stuff seems to be priced a little on the high side, is it one of those get what you pay for things or is there stuff the same as others just priced higher? If anyone has any rebuild kit recommendations I would appreciate them

I personally have bought 2 of their rebuild kits for 2 separate Np231 t-cases. It is pricey but it's a pay for what you get. Their rebuild kit does include a new chain which other companies do not. I have been very happy with them.
