Read the fine print on the Chinese knockoffs via the Bay.
Some of those have no metal frame either.
You're expected to swap out the frame from your original 'blad screen.
Daniel,
If you get hardup, PM me and I'll dig up one of my screens that came on my 500 c/m. These are pretty dim with no focussing aids.
If I were you I'd splurge for a decent screen though.
At least you'll know it will be close and it's immensely easier to focus with a decent screen of your choice.
Hopefully whichever you get will not have to be fitted to your body but it's alway a good idea to have the screen calibrated to your body when you get that body CLAd that you surely budgeted for.
