JoomlaShine is not your every day template club developer site. They have fewer numbers of templates, but they focus on the releases they put out with strong support and updates. Their philosophy is that a template is a piece of software, and they develop and support all of their releases with this mindset.
Also, every template they release has a free version available and two paid versions as well, so you can pick which level suits you and your project best.
Their Pro Standard versions are available at $39, while their Pro Unlimited level goes for $59.
