I guess this is for one of your MEMS chips?

What is the spec of the board's environment temperature?
How big may the oven be?

And I would agree with Bob that building your own oven would be
actually a good idea. It is not that difficult. You need a rough
estimate of what your thermal mass inside the oven will be, an
estimate on what the thermal resistance between the inside and
outside is, then can apply standard control theory to design
a PI control loop to keep it stable.
