If you were going on a modem-buying spree, I think testing a K56Flex might be fun for a change. The industry says that flash upgrading these two modem types, would give *identical* V90 behavior. That was bullshit, based on my testing. The original "flavor" of each, leaks through. Even with the V90 firmware in place, the K56Flex works better with a K56 front end. This is why I ended up with two modems, flipping back and forth depending on what I was calling into. The IT department at work, lent me a K56Flex to test with, and that's when I decided to buy one. X2 _________ \___V90 K56Flex ____/ I don't know an easy way to produce a list of K56Flex products. That list I found is a start, but it's highly unlikely to be perfectly accurate today in 2017. Since you're in the used market, and since the V90 era was quite a while ago, I suppose items in the list would still make sense as choices. If the product description includes the K56Flex terminology, that means there is a Rockwell or Conexant-branded ACF chip inside. The example I gave, of the picture of my DiamondMM Supra, shows that my chip was an ACF type. And Rockwell/Conexant is the K56 camp. ******* There are other ways to debug dialup modems. The modem records the performance of the frequency buckets in the 0-4KHz voice range. After a dialup session completes, and the modem hangs up, you can use a particular AT command (from Hyperterm) to dump the performance data. However, I'll save you the trouble, and tell you not to bother with this :-) I didn't find the data all that impressive looking. It looked pretty random to me.
