I am looking to by a Under Counter Manual Cash Drawer. What is the cheapest option available?

The cheapest option available is the PN-350T Heavy Duty Cash Drawer Touch - Compact : http://www.posnow.com.au/store/cash-drawers/heavy-duty-cash-drawer-touch-compact 
How this Cash Drawer works is, with a push to open and a push to close and at the end of business you can lock it closed. For this Cash Drawer we also have mounting brackets available for additional security. - http://www.posnow.com.au/store/cash-drawers/under-counter-mounting-brackets-for-posnow-compact-cash-drawer
