It's much more mature and feature-rich than I was expecting and when we had a few initial issues Gord was very quick and helpful in his response.
Highly recommended to any music sites who'd like to sell directly.
The developers are very helpful and responsive and even in the short time we've been using the component they've added more and more features.
Not only does it provide a slick interface for the most common things you will need to do on your pages it also provides a wide range of more advanced tools (image editors, thumbnailing options) which are powerful and well-designed.
Redshop is extremely feature-rich and continues to mature with each release that is brought out, new features being added all the time. It employs a very elegant templating system to make it easy to adjust layouts from within the component itself (although you can also choose to use MVC template overrrides) and the support via the forums is second to none - Ronni and his team are just brilliant and seem to genuinely want to create the best products available.
The only slight negative comment I might have is that the rate of development was almost *too* fast with revisions coming in thick and fast whilst we were developing that initial site meaning that we had to redo a lot of work, however as the product has grown more mature things have become more stable.
But overall a great product to use - recommended to anyone.
