I was starting to wonder about SLR customer service myself.

I e-mailed SLR twice asking them questions about the 5100's, and then actually ordered the Bilsteins from them online. So far I haven't received so much as one e-mail back, other than the automated response one when you make an order.

I haven't hit the panic button yet, as I realize that SLR probably gets tons of e-mails a day and would have a hard time answering all of them.

But, some response from them would be nice.
