In sokker: "I believe Sokker.org has a similar system and doesn't charge you just for listing (I may be mistaken on this though)."
Sokker charge you always, and actually heavy, each time you sell. If you put on almost 0 you don´t pay but if you want some reasonable minium floor the charge you.
In my opinion the system in HT have worked very well.
Just for clarification because English is, as you no doubt know, a very silly language: when you say:
"Sokker charge you always, and actually heavy, each time you
sell"
Do you mean that when you offer a player for sale, you are charged, or does that only happen if the player actually receives a bid? My understanding is that you mean the fee applies simply for offering the player for sale (by putting him on a transfer list) but it could be read either way.
