The huge advantage of a visiting DPE is that you can do a checkride in your own aircraft - the one you trained in and the one you know well.
Going to the USA means cheaper flying (though nowhere near as cheaper as it would have been 10 years ago) which makes financial sense if you are going to do a lot of training, but you have to pay for hotels and the airline tickets and the whole thing makes little sense if you will then be flying a different plane.
The main safety thing in flying is currency on type and this is why so many people have paid visiting DPEs. It focuses the training and the checkride (which is also a training flight) fully on the plane you normally fly.
For a 61.75 only, it cannot make sense to go to the USA just for that, if you can get it here.
