first surface mirror

Hi,

Sorry if it's not the right newsgroup, but may be you could help me.

I'm looking for a first surface mirror, not very expensive  around $10.00
size 120x165 mm. It's not for scientific experiement just for reverve a
picture in a super 8 projection system.

Do you know some dealer of such products

I would like to know if someone bought some mirror from
http://www.anchoroptical.com.

Are their products good quality ?

Thanks for you help.
