I will throw my 5 cents in here also. I have a 05 Mastiff and in someway like the Rocker, it was a frist year project. So there was some problems, but nothing major. It has never failed me and as far as reliability goes, I have over 15k on it now (would have many more but tend to play in sandboxes for months at a time).
I have had HD before and enjoyed them all, but like many other bikes, I had issues with them also. LEARN TO WRENCH YOU OWN is good advice.
Since I have my BD, I have loved it and do admit it gets more looks than any other bike I have owned. That said buy it for yoursefl and not what others thing, but do enjoy the side benefits if you get a BD.
If you go with the Ridgeback, do the maintenance, do not abuse the crap out of it, and most important ride it every chance you get.
On videos, there is some in the Galley as already pointed out and here is a link to one of mine. If you get yours be it a BD or HD, you are more than welcome to come join us for some riding for the NE and SE boys tend to get together a few times a year.
