.. both models mentioned would be very good purchases; depends on if desiring local purchase/online. Samsung does have v. good processor. Though, believe LG has slightly better blacks.
regarding accompanying items: no calibration equip., but a search thru the Forum, you'll probably locate some suitable settings which you can adjust to taste.
cables: with Cable/Satellite: if non-HD receiver (which would be waste), it will connect directly out of receiver w/ coaxial cable. If HD receiver, purchase HDMI cable (4-6ft length. 28awg-more flexible) thru the Forum sponsors (Blue Cable or Monoprice) or thru Amazon; should not cost more than $10 for one HDMI cable.
DVD player (Blu-ray): with standard player, you may be able to connect HDMI cable (or) Component (Blue/Red/Green plus need separate digital audio cable). Same for Blu-ray player, and believe Playstation 3 player.
with OTA (Antenna): plug coaxial directly into set & do ATSC search (TV menu function) for local HD-channels/local networks/affiliates. (Some SD channels will sneak in also; shown as 480i)
If you haven't jumped yet.... You might want to check out the Zenith Z42PJ240 (carried by Sears/Kmart - maybe others). The Zenith is basically a re-badged LG. Essentially the same set, but with a lower price tag.
