Oops! Snapped my wide angle diffuser panel off!

[Nifkin]

Dropped my flashgun t'other day; sturdy thing it is, not a mark on it and still works fine, but the diffuser panel snapped! I have seen this excellent post here explaining how to DIY replace the panel, but I was just wondering if anyone has paid to have it done, where and for how much? Surely this delicate little thing gets snapped all the time! It's not critical to how I use my flashgun, but it'll niggle me until I get it sorted!

Cheers
