I'm currently running TotSK using a mashup of OSE/LotFP/LFG and my own hacks and ideas (planning on putting my system out there someday... But thats another post entirely). The reason I picked up TotSK was to have a ready to go dungeon for players new to OSR, so I could focus more on my ideas on mechanics and filling out the setting outside of the dungeon. This module is awesome! I read through it once or twice (only took a few hours) and now only brush up maybe 30 minutes before each session so I know what the players are likely to encounter. Simple and easy to use at the table, this module allows me to focus more on the fiction and what I am trying to achieve mechanics wise. The lessons taught in the adventure are easily learned for both players and GMs as well. So far, we have only had a few character deaths, but none of them felt cheated. I would recommend this adventure to anyone wanting give the OSR a try, or anyone just needing a simple, easy to use adventure to get started.
