Now it may be different where you are but I've found a better soloution.
Viovio Website
I know many people don't like to use album producers that are available to the general public, but I have decided this is the way to go with a particular provider giving me what I need, virtually equivilant to askuka, but much cheaper.
Viovio offer some of the best prices around. Now at this stage they don't offer the 10 x 10 as a hardcover (image wrap) but do offer that as a 12 x 12. The 10 x 10s are leather or suede with inset cover. You can get all different styles and sizes.

I do all my proof albums through them now and the results have been fantastic. I do US Letter soft cover portrait style, and print the contact sheets to PDF from Lightroom, and add a cover design and inset pages. You can see an example here:
Proof Book - Viovio

Ok - quality comparison.
I've done this extensively.
Asuka is slightly higher in quality with the inside pages - I mean you can tell when you take a magnifying glass to it, and the differences are very slight.
Cover - for hardcover wraps are virtually the same in quality. No noticable difference.
Page material. Asuka page material is higher sheen. The silk finish of Viovio is more of a matt finish.
I haven't yet recieved the Black Suede 10 x 10 I ordered recently, so I can update you when that comes, in about a week.
Try them out. At least for proof books to start with. These are fantastic options.
Couple of other points.
Price difference is Viovio around $35 for a 40pp leather/suede book. Auska (for me) with leather/suede $450 or so.
Even the Hard cover Asuka's for me are around $250.
On the Viovio you can remove their logo, either by paying a $10 fee or buying professional membership.
Let me know if you have any further questions.
