Love 'em. Wish I had more time to make new maps.
I usually print them out on standard paper from my ink jet and then cut and tape them together. It does not take as much time as you would think.
Here is a snapshot of one:
Also, if there are hex elements you like, there is nothing stopping you from cutting them out separate to use over and over like the hex packs. There are four turrets in the map above which I cut out as single hexes so I can use them on any map in my collection.
