I got silver Velocity Vs / Formulas from Bells for just over $200 on ebay. At first I was going to get some Fusions, machined front and non-machined rear, but there are so many deep V sets out there at good prices right now that I just went with a stock set, which I am guessing are machine-built. I figured the silver machined rims would be the most versatile in the long run, plus I think the machining looks fine on a silver rim, regardless of whether I have a brake (I have a front brake).
My lbs looked them over and told me not to bother with tensioning/re-trueing until after I ride them for a while, and then only if they start pinging or actually go out of true. They seem fine.
Also - I've read some gripes about Bell's delivery times but I bought on a Friday or Saturday, they shipped on the following Monday and I had them on Wednesday. I got several emails where they had printed a shipping label, then canceled it, then printed it again, but it didn't affect the delivery time.
