USB Charge: 5$
If you want a custom jewel, buy one first and ship it with the PSP. But for the install and SR LED's around the jewel: 15$
LED Swap: 5$
I've never done dual nubs, so I don't want to attempt that. If you really want those, you might have to find someone else.
Shipping to US both ways: 24$ for Priority Mail.
Total, (subtracting the jewel): 49$
