Flipmats are imho the best option for portability, ease of use and price. Dry-erase, wet-erase, permanent - you can use all of these markers. They come in a bunch of shades and designs and have a premade scene on the flipside (sample dungeon, market, cathedral, forest etc). Use them all the time.
I also have Chessex battlemats (and the ludicrously sized mondomat) but have found them a complete hassle to keep clean - they seem to want to absorb pigments. Really annoying. That said, I'll second the recommendation for children's washable markers - nice, cheap option for wet-erase mats.
You can also make your own easily and cheaply. Paper grids are easy to come by, either from office stores or in any number of RPG products (the 3e DMG had one in the back, as did the yellow basic box, as well as D&D minis starter kits, Fiery Dragon's Battle Boxes etc). Take one of these, cover it with transparent, sticky plastic film (the kind of stuff used to cover textbooks in school) and presto: one battlemat. Just as useful as a store-bought mat and a fraction of the price. I've made about 6 or 7 of these and they get as much use as my flipmats.
