Just a heads-up for everyone looking for an R4. RealHotStuff.com just got a shipment in today of the latest black version of the R4. I have compared all the usual suspects selling carts and RHS prices are excellent, and even more important their customer service is great! I ordered my R4 at 2PM and I got a confirmation email AT 3PM that it will ship out today via DHL, and I will have it in two days at my door. Best part is, the DHL shipping is only $8. Can't beat this deal anywhere else I have seen. Their site still says "out of stock" on the R4, but the representative I spoke to on the phone said they had not updated the online inventory yet, and they do have em ready to ship, so just place your order if ya need one. I have had two friends that have dealt with them in the past and have highly praised the way RHS does business. I actually called them on their toll free number with a question and I got an answer on the 2nd ring. The person on the phone was knowledgeable and really helpful. Their forums also tell the tale of a lot of happy customers. In addition, they have an amazing 90 day return policy, I don't believe anyone else selling carts offers that. Now go get your R4 ALREADY!
