In which case, I can entirely see why you've chosen US over UK.
Its still an interesting, if not annoying, issue with google that the local searches are so... well... local!
As you say, US hosting charges as SO much cheaper than UK - take Dreamhost for example!
An interesting read on this topic is on Matt Cutts blog:

Quote: "An SEO or two has been holding my feet to the fire about root pages of .com’s that are hosted outside the US. Barry has talked about the issue a little bit
here. In some (pretty rare) circumstances, you’ll see the root page when you search site:domain.com on google.co.uk for the “search the web” option but you won’t see the root page when you switch to “search pages from the UK”. I thought we’d nailed this issue in December, but we found another way that this can happen. I believe a fix has been submitted and is percolating its way through the system. Of the ~7 examples that I know of, I believe all but one is working now (and the remaining site is doing a chain of like five 302 redirects to weird/long/deep urls). However, if you 1) have a .com that is hosted outside the US, 2) searching on (say) google.co.uk for [site:yourdomain.com] returns your root page and all your pages for “Search the web”, 3) if you switch to (say) “pages from the UK”, the root page does not appear but the rest of your pages do, then this paragraph applies to you. I’d wait 4-5 days to let this second change percolate completely into our index, and if you still see the behavior after 4-5 days, please leave a comment with the name of your site."
