Looking for a new keyboard

Ok so I am looking to replace my "logitech access keyboard" that is ancient and ugly but somewhat comfortable. I'm wondering if anyone knows of a mechanical keyboard (not rubber dome)for like $30 I highly doubt it exists but if someone knows of one let me know. I am being very wishful, I know.

If it's not second hand, I doubt this exists tbh.

watch ebay for "for parts or not working" and be ready to fix it

edit: apparently alps keyboards are cheap, never used an alps switch so i won't vouch for them, but they are mechanical http://www.ebay.com/itm/ALPS-CL-18802-BELGIAN-KEYBOARD-AEI-001-5080-/350441091456?pt=PCA_Mice_Trackballs&hash=item5197eab180
