Online Auction Software/PHP-script/module

[timoro]

Hi guys

I have been looking around for a good online auction software/php-script and it is really hard to make a decision which one to buy because there are always pros and cons.

I have used cmsmadesimple for many different solutions and I am very happy with everything about it - possibilities, progressive development, support etc - I can say I love it.

So, my question would be:
Are there any plans or steps towards an online auction software module like ebay?
If not, are there developers who are willing to do this in close collaboration (not for free, of course)?
Or can anybody recommend a powerful open-source online auction software?

Looking forward to your answers!
