On a related note, is there a good & easy way to destroy data
CDs? The shredders I've come across with CD slots just scratch
the surfaces up a bit rather than break them into bits.

I had a large pile, and didn't like the idea of feeding them all through the microwave, in case it damaged it.

Does anyone know if you can bust a microwave if there is nothing (or not much to absorb like water) in it?

In theory you can, but decent modern designs allow for that.

Corse all bets are off with the cheapest **** from china.

What about a "Tesco (supermarket) value microwave" that cost £25?

Dunno, thats the big problem with the cheapest chinese stuff,
you basically have to try it and see if it does what you want.

Corse if you do kill it you likely can just claim on the warranty with that one.

Corse one from a garage/yard sale would likely be much cheaper.

Dunno about there, but here you usually see a working
microwave most weekends at the garage/yard sales.

Will it overheat as there's several hundred watts of microwaves
with nowhere to go but the dummy load in the magnetron?

Normally not.

Cut out or it can just absorb it?

Just handles it fine.
