magento ebay integration

Hi, I have an existing magento based site www.officefitness.co.uk. This project is to create an Ebay equivalent using proper magento integration. I have seen the M2Epro extension for this but did not know if that was the only way to go about achieving this. Currently the site only has 5-6 products but please quote for a 15 product integration Please only quote if you have a reference magento / ebay integration that you can supply as a reference site A good reference site is [login to view URL] to show the sort of thing I am looking for Thanks Paul
