You can use a LK201 or the seemingly less desirable LK401 with the VT320. There are a number of LK201s on eBay right now for reasonable prices. The cheap ones are always going to be untested/dirty/possibly missing a key or two.
The thing to do for MMJ converters is to get a MMJ cable and an adapter. The 9-pin I use is a H8571-J, I don't have many of those so I can't provide one. The 25-pin I use is H8575-A, I have a few of those so if you wanted to buy a MMJ cable and a MMJ -> DB25F, I could sell you that combination for a reasonable price. I have a huge spool of DEC OfficeConnect branded Spectra-Strip flat cable, a ton of MMJ crimps, and the necessary crimp die to make up cables of whatever length you'd like. Contact me off-list if you're interested.
