I got a Korchmar (no straps) as my first bag over 12 years ago. I love it!!!! Awesome quality, I paid $200 for it. I have had a little bit of work done to it, new handle, but it is still tough as ever.
I got a second bag as a spare, same style and brand. The new one is very flimsy cheap. Sent it back for handle and latch and the innner board in the lid was broken, they did not fix it. It is junk!!!! So, now i have nothing good to say about Korchmar. But, the straps would make it more durable.
