Where to get transparent keycaps?

[jello]

I currently own a couple of backlit mechanical keyboards. I'm now getting tired of the old keys and looking forward to change them with some keys which are transparent and allow the light to pass through.
Which would you guys suggest for good quality and meet the requirement above.
I can go probably around 50 to 70 bucks.
P/S: I have the Razer BWU and CM Storm Trigger.

This is the only place I know of to get clear keycaps:
