dock for T22

[zver17]

I am looking for a dock for a T22. searching on ebay shows many docks that look the same but have different part numbers, and all claim to work with "T series", eg, P/N 2631-2OU. Can somebody explain why so many different P/N? I thought there are only two docks for the T22 - the "dock" and the "port replicator"

Also, is there a dock for T22 that has 4 USB ports?

Finally, I will be using the dock as a security device. How strong is the lock on the dock and, once locked, can the T22 be removed without causing extensive damage (eg, assuming the thief steals both items and has access to tools)?
many thanks.

Get one of the Mini docks for the t4x series, they are backways compatable with the older t and a series. Its has 4 usb ports and the security key lock.
