The general consensus seems to be that the FTDI chipset is most
compatible and most reliable. You can find products that use the FTDI

I'm not affiliated with FTDI nor ByteRunner - just what I've heard "on
the block"...

I went through this a while back and my experience was that many of the USB 
to Serial Converters did 
not work in all applications.
 
I did try an I/O Gear one and, although it worked OK for rig control, it 
did NOT work for RTTY FSK keying.  This is where I believe the FTDI 
requirement comes in.  I ended up getting the Keyspan unit and it worked fine.
 
I don't think you can go wrong with either the Keyspan or Byterunner 
solutions.  I can't vouch for any of the others.
