This gets very complicated and confusing to me. To sum it up, from what
you said, it seems like there is V90 / 92 and K56 Flex. The two basic
options. Since my Sportsters have never given me a decent connection
using XP, I want to try something else. Since the Sportsters are V90/92,
I assume I need to try the K56Flex. Is that correct?

This Supra Express modem says it has BOTH the V90 and K56Flex. Is that a
good choice for me, or is there something better (another brand)? 

What should I be looking for? Model numbers will help a lot more than
all this highly technical info. I cant see what chip is being used when
I look at modems on ebay or whereever.
