Battlemat, Miniatures, MasterMaze and Pens
Master Maze stuff is absolutely great. We use it all the time and it is wonderful. Set up time is slower than drawing but the visual enhancement is wonderful. To take a look at some of our battles go
here.
I have spent little over $250 dollars for MasterMaze stuff, but I got it all from eBay. I was able to get most of it at very reduced prices. Currently we have 3 cavern sets. A Rooms and passages set. Wicked Additions I and II. And the Ogre's Den. I can't stress this enough if you have time and patience look at getting these from eBay. It will save you tons of money that you can then spend on miniatures.
When we set them up we don't use the bowtie connectors. It takes too long to assemble / disassemble if you put use those.
For miniatures we use any available. GW, Reaper, Ral Partha, WotC, etc. We usually try to have them painted but any that represent what we are fighting are good.
We also have a Chessex Battlemat for those combats where we don't want to spend the time building it with MM.
As far as pens go. Make sure that you don't use the whiteboard markers. Those are only for non-porous material and when used on a Battlemat you will be unable to erase them. The Crayola Washable markers are too watery and some of the colors (RED, ORANGE) will not come out unless you clean them out immediately. The Black and the Blue work alright.
The best pens I've found are made by Staedtler. The colors are clean and bright and they dry fast, so no smearing. They come off with a plain damp cloth.
Make sure you get the non-permanent ones. They do manufacture permanent ones that are a pain in the ass to clean. You would have to use alcohol to clean those out.
Staedtler Non-Permanent pens are hard to find in your local stores unless you find an arts supply one. I ordered mine online from a place called Shoplet.com. They had the cheapest delivery pricing and I got the pens in two days.
Good luck on your search.
