I had the same dilemma, but mine was more about cost. DF costs a bloody fortune. No dispute it looks great and you get what you pay for, but I don't know anybody who could afford a complete set of DF. I went with a Crystal Caste Dual-Sided Square/Hex Battlemat (the largest size, and it is huge). I like the battlemat as it allows us to just draw out whatever we need and so is much faster and more precise than DF. However, my co-DM has zero artistic talent and so it doesn't look that exciting, but it is precise!
