Has anyone here used/developed for x-cart? I'm considering using it for a site I plan to build, but there are a few features that I'd like which it lacks (but it's the closest tunkey/open source solution I can find to match my needs).

I was wondering has anyone here had any experience using it? Also, for the few extra features that I'm lacking, my PHP skills probably aren't good enough to build them myself so I was wondering if anyone in Ireland/here has any experience developing for it, as I may need to pay someone to bring me that last few steps towards being able to deliver the solution I'd like.
