Anyone recently moved to WPEngine for Wp Hosting?

I am considering migrating my sites to WPEngine. I am mostly interested in improving their page load speeds, while minimizing support and upgrade issues as much as possible. Price is NOT a concern.

My sites are very simple with Thesis or Woo themes templates and few plugins. I may want to add WisdhList Member, ShopIntegrator, or OptimizePress at some point.

Suggestions/comments from actual customers would be appreciated.

Thanks,
Paul
