Here's a pic of my current set. As you can see, it's not that fuggly. This is basically the same set I've been using for about 20+ years (give or take a die) except I recently added the zocchi-pack, the funny d7 and some similarly colored d6s (From Dragon Age RPG.) The little wood-colored d6 is actually wood, and it's a d3, 1-3 in red & green, it's a super cool d2/d3. I wish I knew what game it came from. The d10s are from various GDW games, they're also Gamescience. The d30, I've had for years, it's an Armory "precision" die. It's not nearly as high quality as Gamescience dice. It has lots of chips now.
Another option, so have somewhat matching dice is to get the White version of the d7 and match them with these d6s:

The d6s are my most used dice, I roll then constantly. They're good for rolling all kinds of checks, ability scores, etc. so I didn't mind having them contrasting the rest of my dice. With those, the casino looking d7 doesn't look that out of place.
