Well, I thought we had beaten this horse to death....so if someone complains, it is on your head

The integral compression lock (that is the correct term) is in terms of function completely different from a Chris Reeve style integral frame lock (also correct term). It may look simply inverted but there are two essential differences: The first is the direction of the force acting on the lock. In a frame lock the force is ALONG the cutout that forms the lockbar, or if you will, from choil to butt. In an integral compression lock the force acting is TRANSVERSE to the cutout or from bottom (where your fingers would be) to top (were your palm is, when holding the knife. The lock bar is further wedged between the tang and a stopping pin. This means that the lock bar is far less likely to slip from the tang (better reliability) and the force is acting over a much shorter distance INTO a stopping pin, which should make it much more easy to engineer a stronger lock and the numbers on the available models shows that the lock strength on the compression lock models is among the strongest locking mechanisms available.
From a technical point of view, considering the way the locks are loaded, there isn't even a remote resemblance between a frame lock and and integral compression lock. They are as different as a top wing airplane is to a bottom wing airplane (not exactly the best comparison, but I hope it gets the point across).
I also disagree that it "just requires some getting used to'. Considering that the OP stated that he has trouble manipulating a backlock and is looking for a framelock, it seems pointless to suggest knife with another lock on the top of the handle.
