I recently had the same delimia. I test rode all three bikes that you mention. I like some about each one but I truly found the 09 Silverado to be the best fit for me. I say if you found one for $8K, buy it but that is just me. I do suggest that you test ride each one, one right after the other and sleep on your final decision.
Just got a 09 V Star 1100 Silverado and love it. Still have a 93 Virago XV535 and love it as well.
