The best discount coupon code contribution to use?

[Broadsword]

Hi,

 

I have looked through this forum and through the contributions but there seems to be a few problems that need ironing out with the contributions ive looked at.

 

Before i go downloading and installing i thought i'd ask you guys if there are any recommedations on a stable contribution.

 

I'd like a place where a customer can input a unique discount code at checkout (but before the final conformation screen) where the codes are either automatically generated or manually generated - or both - and the discount can be altered.

 

Any suggestions would be appreciated.

 

Thanks
