I've been using MyThemeShop for almost a year now and honestly can't say enough good things about them.
They are extremely quick to respond, give helpful insights, go above and beyond when helping, create excellent theme designs with awesome code, update themes regularly, and expand usability to their users with their plugins.
It's almost impossible NOT to buy their products.
Not sure if this exists, but maybe you guys could create a community where members such as us could give you ideas on new themes, plugins, etc. I think it would only add to you guys' value.
Thanks for all you do!
