The answer can depend upon the country where you are located.
Assuming you are in the USA, consider getting a Medeco M3. They are very difficult to pick, and resistant to forced entry. They are really only bumpable theoretically or under controlled conditions, so from a practical standpoint you won't have to worry about them being bumped open. You won't find them at Home Depot, but you should be able to get them at any decent locksmith shop. They have key control enforced by the manufacturer fo you'll also be protected against an employee making unauthorized copies of the keys. You can get copies made where you buy the lock, but you'll need to have the authorization card that came with the lock in order for them to make duplicates.
If you go with the Schlage Primus as Linty mentioned, make sure you get the newer Primus Everest. The original Schlage Primus is no longer patent protected so unauthorized key duplication is a possibility. The Primus Everest is resistant to forced entry, difficult to pick, and is also difficult (if not impossible) to bump.
If you want something a bit more exotic and is even more secure, get an Abloy, although availability of these locks is an issue in the US, and getting key duplicates will be very difficult.
