Hey Cazio-I am a newbie here and used to wonder the same thing. IMO - if you are seeking performance you can't go wrong with any of the three ( SR101-77 or INFI) I think the big ticket Busse is just the king of the crop. It depends on what you are looking for I suppose. Collector- user or specualtion.I think many just feel that the steel has a very good ROI which is rare in the world today. If you check out Ebay right now you will see SODs selling at double the cost. Supply and demand and the demand is super high because of the great performance and also beauty of these knives. So- join the addiction.......oh yeah- forgot to mention the addiction. Well- now that I messd this all up one of the JYDs will pitch in. Just my 2 cents-Merry Christmas <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
