Anyone thinking of building or migrating their OS store?

I build a web store with CakePHP because all the opensource solutions proved to be to slow or too expensive to modify for my clients.

I'm at a stage where I would like to see it head to head with other stores and for that I will build some import tools for popular platforms like opencart and co.

So if anyone is building a store or would like to compare the speed and UX with mine and would be willing to provide data for import please get in touch and let's see if we can help each other out :)
