composite curing oven temp controller

Hi guys, i’m planning on building a curing oven but i need help with choosing a suitable temp controller / PID. what should i be looking for?

thanks.

something with a ramp/soak function is nice to control the whole process, and the ability to program enough steps/multiple programs is a plus too.

thanks which make would yo recommend as well as a link will be appreciated.

something like this: http://www.ebay.com/itm/PID-TEMPERATURE-CONTROLLER-W-30-RAMP-SOAK-SSR-OUTPUT-/110627498979?pt=LH_DefaultDomain_0&hash=item19c1e9abe3

or the a whole controller box like this:
