If you find a Trachycarpus fortuneii (windmill palm) or Rhapidophyllum hystrix (needle palm) you should think about purchasing if the price is right. The windmill can take down to 0F if it is old enough (younger specimens will need protection). When they have 5 feet of trunk or so, they should be fine, but I am no expert on this palm, as I can only grow it indoors, because my climate is too tropical to grow them outdoors.
Needle palms can take more cold, and they don't form much trunk, so it will always be small enough to protect. When young though, they can be damaged by below freezing temps. This palm is really variable when it comes to age and cold. When old, they are probably the most cold tolerant palm in the world, but when young they get damage and often spear pulls at temps where Sabal minor isn't damaged. I don't think any palm is long term in 5b though, so keep that in mind when planting. You really need to be in at least 6b to grow any palms with no protection.
I still say you should look into getting a Kentia palm for indoors. They make wonderfully tropical specimens that can even form trunk indoors and look a bit like a coconut, but they are the masters of the indoor palm world. If you put it in a room with a window to let light in, and you don't over or under water them, they will be one of the best house plants in the world. I've got 1 indoors that has 3 times the speed of the one I've got outdoors, they just love room temperature. These seeds take months and months to sprout though, so you're probably better off buying one. Post something in the "palms wanted" forum, and you may get someone who can sell you one. Here is mine as of today, it is 5 fronds from trunking, so probably 2-2.5 years
