I ordered a "custom logo" controller S jewel on March 2, 2005. I received the jewel on March 13, 2005 (via USPS priority mail, from FL to NJ). Total cost of the jewel was $10.00, plus $4.00 shipping (which endede up being slightly less than actual shipping costs... neat!).
Ordering online was quck and painless. I just uploaded a pic for my custom jewel, filled out my info, and I was off. The guys at warpedjewels sent frequent order updates via e-mail, which is always good to see, for peace of mind.
As for the product itself... it looks fantastic. Shape and size is an exact match for the regular S-jewel. It has that same bubble and gloss also, although the material is a bit harder. The only noticeable flaw I can spot is a slight sag in the bubble near the bottom portion of the jewel (if you look at it from it's side, one side is thinner than another). However, when it's on the controller it's completely undetectable, and not a bother at all (and I'm one of those guys who freaks out over tiny details).
If you're looking for a custom controller jewel, I highly recommend these guys. Their workmanship is very polished and professional, and I'm very happy with the service, and the final product. Definitely worth the wait.
One caveat: if you do order a jewel, do not assume that you have received an empty envelope, as I first did. My jewel was taped to the back of my invoice, in a little fold of white paper (a perfect match for the white invoice), and I completely missed it. Keep your eyes open, as it's small and easy to miss.
Buy form these guys with confidence.
