Yes - I owned an FTDX-5000D for a very short time and now own a 
competitor's rig.  Feel free to email me for lots of details, but here 
is some advice:

1. If you plan to use the 5000 for CW work, ask the dealer if he can 
guarantee that the "short dits" problem is fixed on the unit he wants to 
sell you.  Make sure he'll take the rig back and pay the return shipping 
if you find that the problem is still present.  He may not be able to 
make the guarantee.  Do not assume that the fix has been factory 
installed as alluded to in the ARRL review.
2. If you purchase the 5000 and plan to use if for CW, be sure to look 
carefully at the CW waveforms in both QSK and semi-break-in modes.  DO 
WAVEFORMS.  The monitor signal appears to be almost unrelated to the 
real signal being transmitted.  Listen to the keyed CW signal on a 
separate receiver while sending a string of dits.  If it has the short 
dits problem, it will be VERY apparent.  If you don't have an 
oscilloscope capable of looking at the transmitted RF waveform, another 
approach is to listen to the signal on a separate receiver and feed the 
audio to any audio editing program via your sound card.  Then look 
carefully at the dit and dah lengths compared to the spaces and examine 
the waveforms in both QSK and semi-break-in modes.  Look for things like 
overshoot at the leading edges or distortions in the leading edge of the 
waveform.  If you see those things, you WILL have key clicks.  If you 
see problems in the waveforms, return the rig and get a refund.  Or, you 
can wait until Yaesu has a complete fix, and pay the round-trip shipping 
to California to have the fix installed.

The SM-5000 is interesting in its shortcomings.  The speakers are 
excellent as everyone has reported.  The scope takes last place behind 
every other I've seen, including that in the Orion II.  The contrast and 
brightness is exceptionally poor, and the designer's idea of "averaging" 
differs from every other.  Otherwise, the transceiver is a joy to use 
and the receiver behaves as advertised.
