could be - but daft as it sounds, I'd really miss the noises.

And yes, they do tick all the boxes.

Now, the odds are the printbed won't be totally flat. I'd suggets some 3-5mm glass and a couple of small bulldog clips. I initially used 1.2mm poundland glass on mine and it just bent to the same shape as the printbed (which was ever so slightly domed in the middle) I've now got a 3mm sheet of aluminium on it and it's perfect.
But any glass thick enough not to bend will work just as easily.
