Thanks very much for your responses guys, I greatly appreciate them.
I have no problem riding a Giant, despite their popularity. I've been riding since 1991 and in that time have ridden an enormous number of bikes. I have always been of the opinion that boutique brand bikes (Ellsworth, Pivot, etc) are, despite being good machines, a bit of a wank: same performance for twice the price, and for what? Essentially, in terms of the ride, a different set of stickers! Therefore the fact that, if I purchase my 4th Giant, I will see a large number of them on the trail, is not something I give half a shit about: if it's a great ride at a great price, that's all that matters.
Looking at the specs I'm not sold on the 2012 Anthem X, much lower spec list than the 2011 model, hence the lower price tag: no UST wheelset, RP2 as opposed to RP23...still a good spec for the coin, but not up there with the 2011 model IMO. Based on spec alobe I'd much prfer to pay $3600 for the 2011 model than $3000 for the 2012 version.
In terms of the frame gussetting, I can't say that I've heard of any Anthem breakages; they may well have happened but I don't recall any publicity in regards to such an issue.
I've looked at a myriad of other bikes online and while many of them are great rides and good value (eg: Scott Spark) they're not in the same BFYB category as Giant's of similar price tag and purpose.
Oh and Todd, the cheque's in the mail mate, haha!
