Need Some Advise on Shipping!
Note that Danzas has not been extending their special Santana tour rates to non-tour shippers for several years, which is really a shame: that was a good value with reliable service.
FedEx Ground seems to be willing to take oversized with the prerequisite premium charges; of the various big overnight shippers FedEx is currently my pick: I've had a few bad (really bad) experiences with OOOPS (UPS).
Greyhound has gotten very good marks just following the postings of folks who have used them: very low cost compared to other alternatives; however, you must be attentive to the logistics on each end of the journey.
Any commercial, over-the-road shipping company (Roadrunner, etc...) will also handle your shipments; however, residential delivery is often times a problem or carries a big surcharge vs. delivery to a commercial business address.
If you and/or the person selling / buying a bike have a good relationship with a LBS, having any shipment picked-up / delivered there (UPS, FedEx, DHL/Danzas, OTR, etc..) will usually save you $$$ if a drop-off / service center isn't convenient.
