Seeking dry erase board with one-inch grid

[phindar]

I picked up a 8'x4' sheet of white panelling at my local DIY for about 12 bucks. Its basically a sheet of MDF with one side coated in a white plastic that seems fairly resistant to all forms of markers. I attached it to a piece of plywood and put some looted folding table legs for it, and now I'm waiting to take it to one of my fellow player's dens so we can try it out. There's no grid (which I actually prefer), but if you needed one you could put one on it. Either way, 12 bucks.

As others have mentioned, I went the $11.00 tileboard from Home Depot route. However, it was a pain to score (and, if you have OCD issues, you may flip out if your hand slips with that Exacto knife while making a line ). However, I wanted a huge battle map (as others have said, these sheets are 4 ft x 8 ft). If you're curious, click on my Flickr photos link to see pics of it (see sig).

One option I considered was these self-stick dry erase sheets:

I'm really thinking that this board is the way to go, but my one concern is the dots. Are they noticable from a couple feet away so that my players will be able to eyeball ranges and such about as well as with the fully gridded squares?

Sorry for the late response, and Thalmin already answered, but I'm in my office now with one on the wall 8 feet away and I can still make out the dots if I try. Otherwise they just fade into the background.
