A best bet are the Barska Biometric Safe with Fingerprint Lock, model no. AX11224, for $149.99 with free shipping. That's $10 under our mention from last winter and tied as the best price we've seen for this safe. (It's a current low by $28.) This safe accepts up to 30 permanent or unique fingerprints and includes two backup keys plus mounting hardware. Four AA batteries are required, but not included.
