My only other comment is you appear to be spacially challenged with all three logos. Let's just take a look at the best logo (#1). I think that "Smart Business" is in way to large capitals. And you would be better off putting "Smart Business Domains" all together on 1 line. Aligned left and right to the "S B C". Which keeps the eyes more clearly pointed at your main logo "S B C".
Personally. I'd also use your sub-text (Premiun Business Domains at Bargain Prices) in your text rather than in your logo. But that also should be aligned left and right to the rest of the logo, if you choose to put it in your logo.
I'd also would not include any TLD in you logo. It'd just extraneous info.
