Hello Aaron,
When you check on the cost of clutch parts with Audi, then you are unlikely to buy genuine parts - even when you take into account the reimbursement on your returned old components.
If you decide to go down the route of aftermarket parts, then the only ( in caps.) make I would use would be LUK, with no exceptions in my book. Shopping around - even on EBay should lead you to be able to buy LUK kits at prices competitive enough not to bother with any other aftermarket make anyway.
It’s always worth investing the DIY savings on the best of parts.
Good luck and kind regards,
Gareth.
