The price is not bad, it depends on how many books you are doing really and then of course shipping. The quality is great they offer a couple different ways these can be bound. The Flash and Question books I have from them are excellent they lay flat no gutter lose you get some ads removed but can keep covers to the individual issues and also mix trades in with the single issues. I would really suggest reaching out to them and see if it is something you are interested in, very helpful with mapping and also design.
I am just not to big on the uniform spine thing and like the different styles of the Flash name, especially volume 4 I am a big fan of that story nice to have that style on that volume. The designs are all done by http://comicbindingpro.com/ they have bunch of designs on the site and really just do a great job on design.
