I have a Garmin Foretrex 101 that I use for running when I am home. I use it as a backup in the field. I learned the hard way that using the GPS to get back does not always give you the same route you came in on. As the Crow Flies does not mean the best route. I have done some bushwhacking as a result of relying on GPS, with a 45 pound kiddo on the cargo chair of my K Marauder, and my wife constantly intimating that my parents were related prior to their marriage. I foresee always having a topo map on every hunt, and more than that, I anticipate buying a new one every year even if I am hunting the same area.
While a BLM or State lease requires access for hunters, some leasees have different opinions. I can't afford a showdown on a piece of land that MAY be private, or MAY be BLM or MAY be State Trust. There is a local survey shop that can print a current, up to date map using the same software as all the GPS guys rely on for knowing what parcels are what. I would like to give a local company business, so I buy maps for each hunting area annually. Waterproof paper costs me about $17 for each GMU. I learned after some confusion last season to also purchase the USFS map of the area, just to head off problems. Sometimes Forest Service Roads are referred to by their County Road numbers, or vice versa, and the S&R guys are more concerned with maps showing access. Use both maps, and a compass, and determine where you are, so you are legal in taking game.
