That's the main reason I chose to do this. 600mm borosilicate and 600mm aluminum are not cheap. In fact, 600mm borosilicate is extremely hard to find. My tabletop was ordered from Amazon for about $40 USD. Very replaceable.
You don't need borosilicate. Ordinary float glass is fine if it is on top of a heat spreader (some people even use it directly on top of a PCB bed heater).
