To give you an idea what the view of the ice is like from section 121, here is a Youtube video shot from there during a Blackhawks/Vancouver Canucks game at the United Center. The video is in slow-mo and isn't the best quality but will give you a good idea what the seats are like.
121 sits behind the player's bench. Tickets are very expensive in this section, I paid $300 for two tickets in row 7, seat 5 for a measly Blackhawks-Panthers game. Great view of the ice but will sit in the upper level next time, a section that fits my budget.
