you need 110 volts on one side of xfmr, which will be installed through one of the knockouts in your panel. On the other side of the xfmr will be where your 12 volt wire connects, then run that wire any way you want to the doorbell chime.

I've always liked the wireless ones myself, no fuss

Depending on the mounting provided, you might find it easier to attach the transformer to a junction box rather than directly to the panel. You can install it anywhere that is accessible and where you have 120 volt power although there aren't many places you can install it without its being unsightly. Junction boxes can be attached to panels using nipples as opposed to wired in with a short length of Romex.
States can help recovery from hurricanes and tornadoes by not requiring due digence or prompt and timely correction of substandard conditions, and by providing continued liability insurance where companies drop homeowners.
