COE actuator brands?

I need some actuators for my storage boxes. Most on ePay are slow (8-12 mm/sec). I need them to be fast (30mm/sec or 1"/sec) and strong (50# or more). Anyone have any thoughts on brands and where to buy them?

I want to keep the price under $100 each. I can buy them from Progressive Automation, but they are in the $130 each range.
