If you would be OK with a little DIY work, Google for things like "reflow soldering with toaster oven". There have been many conversion projects to adapt cheap toaster ovens for hobbyist reflow soldering.

This involves putting in some good temperature sensors, and bypassing the built-in controls to put the heating elements under the control of an Arduino or similar controller.

Some even add a cheap graphical LCD that can show a graph of temperature over time, and a simple interface to let you enter temperature profiles to follow.

I’ve built one of those. They also need a bunch of insulation, heat spreading plates and another heating element to get reasonably even heating.

You can drop the insulation for food use, but thats one of the cheaper parts of a build.

Since temperature is important for reflow (melt the solder without melting your leds and connectors) they have good ways to calibrate them.
