Affiliate Marketing Secrets

Can anyone recommend a good auction script?
I want a good simple one. I will only need GBP currency, as it is a small niche and mainly directed at UK customers.
I have tried a few ones out on trial but some of the functions were a bit too difficult to adjust.
If you are running one – I would like to see your url so that I can get a good idea of it’s key features.
Thank you,
Annie.
