Lets go completely the opposite direction and suggest something totally different.
I had a Crewe book done a week or two ago and the quality is pretty damn good. Unfortunately I haven't printed one with another compay yet so can't fully compare however having just read Raymonds comparison between the Loxley and Blurb i would suggest the Crewe book is closer to the Loxley than the Blurb.
I got the 8x10.5" Hard back photo paper one (instead of standard):
The print quality is up there with the Loxley standard lustre prints, which are my standard choice for any prints. The texture isn't quite there, which lets it down a little but it's only slight, and still better than somewhere like Photobox's standard prints.
The paper is pretty thick, I think the way they make it is stick two sheets of printed photo paper together so each page is around a mm thick (a lot thicker than normal paper). There is very little sign of this on the edges however and I only came to that conclusion by looking at the spine.
Due to the above printing method it means each double page spread is made out of a single sheet of paper (so 8x21") so photos spread over a double page don't have a gap (like the Loxley Raymond mentioned).
It does seem to stick in the middle ground with regards to price. The 36 (I think) page one cost me £38 delivered, whereas the Blurb one is around £28~ delivered and the Loxley one at least £100 (haven't looked at the price in a while and so a guess, it could actually be way over £100).
Sounds all well and rosy then, however there is one "let down", the hard back cover isn't brilliant. It looks a bit cheaply printed and doesn't feel very strudy, almost feeling like too much flex and the spine will start ripping. It's fine, but doesn't really live up to the standards of the inside. I think however you can get leather bound versions, which may be a lot better.
As for printing with Loxley, they do cater mostly for businesses and large orderers however they will also cater for the occasional printer. You just need to download the ROES software (very good BTW) and email them for an account number (it will tell you how on their website). I can see the prices being different for different people however as you have to log in (or go to your set up ROES software) to see any prices. In general however for standard prints smaller than 12x8 they are reasonably expensive compared to photobox (but there is no comparison quality wise) however larger than 12x8 and prices become very similar and can even be cheaper for really large prints.
Anything other than standard prints however and the prices make you cry!
EDIT: Lets put it this way, from my account the cover of the book Raymond showed costs more than a standard Blurb photobook on it's own, the presentation case, more than the cover...
EDIT2: Ahh, I see where you're coming from now, I can "order" the box and the cover but there are no prices for the book specifically. I assumed you meant using Loxley as a whole. I'll have to look into that as I was tempted to order one in the future.
EDIT3: The prices for the Book however are available on the website (once logged in) so if you do get a Loxley account you wll be able to see how much they cost. They do however do an infinity coffee table book which is a more reasonable price of around £70, I have no idea how good they are however, I assume still very good as they are from Loxley.
