...the Limited was a good frame from Japan with a very functional if not spendy components package.
Having said that, here in NorCal (which is supposed to be a pricey marketplace) there are some pretty nice bikes that will require about the same amount of work as that one, in the $400-600 range.
That one does have about as much celeste as you can pile on a bike, which if you're looking for that sort of thing will probably save you money in the long run.
But around here, 400 bucks is right now right at the entry level price for a step up. There's a Rossin down in the bay area that I am heroically resisting right now at about that price. It's not celeste, and it's not a Bianchi, but it's another level up from the bike you're looking at. Not saying that's a good thing or a bad thing, but at least around here it's a buyers marketplace right now.
OTOH, if it's the color you want, and your size, quibbling about a hundred bucks or so on price is silly.
