I'll talk about what I've experienced: the VB GF002, 003, and the carbon speed pinarello grevil clone. They're all nice, but strong preference for the clone, it's such a fun frame, very fast, very road orientated. The VB ones are much less fun on the road, older and arguably not as well finished.
If the clone interests you, Peter is on the forum. Pricing for all 3 are within your budget. Afaik, ican doesn't make better frames (nor worse), but do spend money on marketing and kick backs, so they charge more.
