Yes, do it now, they're having a sale
I actually ended up buying the OG (again) and it has become a regular in my travel arsenal. It's a little small for overnights (curse my need for toiletries!) so I'm eyeballing their Catalina Deluxe small for those times I don't need a laptop. I spotted someone carrying one on a flight back from ATL last month (so sad..."Is that a Lo and Sons Catalina bag?" "It is!").

I have also picked up the Seville because I was concerned that the OG was too big for a personal bag but wanted something "grown up" looking for meetings. The Seville is lovely with it's swap out shell options but there's a catch that I wasn't aware of. The travel sleeve does not fit over the shell. You basically have to take the bag apart, remake it with the (nylon) travel sleeve and carry the leather shell separately. The shell takes up a significant chunk of luggage real estate if you're traveling light. So I end up traveling with just the travel sleeve and insert as my laptop bag, which is OK, but not what I expected. I use the Seville + shell for when I need to go to business meetings locally.
