Looks like a good project.
Good quality 10MHz oscillators are now widely available at reasonable cost. 0.2ppm basic tolerance is an interesting level of performance. I'm well aware of it because it's what's needed for a top quality TV sync pulse generator. Traditionally it was a bit out of reach for a TXCO but a rather low spec for an oven. The ovens were quite big and expensive too.
Now you can buy low-ish cost TCXOs with 0.2ppm stability over a reasonable temperature range. And you have found a low cost compact oven with similar stability.
You can also buy GPS disciplined OCXO modules. No idea of cost: https://www.iqdfrequencyproducts.com/pro...ned-ocxos/
If you really want to push the boat out you can get compact rubidium standards. Prices start at the $1000 level. Secondhand ones may well be very worn out - they don't last for ever. Most people would be better off with a GPS based system.
