also have a look at seagull bags, I've been communicating with them, and they do custom work on the bags, priced like the PAC designs bags, so it's pricey, but you can have them nearly made to spec for you. I'll be placing my order very soon. http://www.seagullbags.com/ also worthy noting: PAC Designs http://www.pacdesigns.com/ Bailey Works http://www.baileyworks.com/ Chrome Bags http://www.chromebags.com/ Bagaboo Bags http://bagaboo.hu/en/bags/
Don't forget Crumpler. https://www.crumplerbags.com/flash/flash.aspx#/english/products.html I even have an old school laptop model (i.e. no longer made) in great condition, if you're interested, PM me.
Bailey Works is top notch. I have one of their duffels and always get comments about it. I have put it to very hard use and it is so far bullet proof. There are different levels of bags out there in terms of quality and design in my opinion. They are; Professional/hard use , Cool design/hard use , Cool design/common man use , Look cool/common man use. Professional/hard use; think; Bailey Works, Aerostich,Cocotte Equipment ; Cool design/hard use; think Chrome (Chrome is almost as overated as Maxpedition), Crumpler; Cool design/common man use; think Timbuk 2,Pac Designs Look cool/common man use; think Patagonia, Eagle Creek, REI. All levels are priced accordingly (for the most part)
