May I ask why, I was thinking of getting a site with them
Google hates duplicate content. Having the same title tag and meta tags for multiple pages is duplicate content as far as they are concerned and this affects your ability to rank.
Since this thread was started, Google has added a section to their Webmaster Tools to warn you if your website has duplicate title tags and/or meta tag issues. If you have a website you may want to consider signing up for a Google account and check out their Webmaster Tools. It can give you a lot of info about your website and whether it has problems that may affect ranking.
