I would get them both now if you love them. Price will keep going up and they are both classic bags. You can always sell them later if you change your mind. I have a love & hate relationship with logo bags and sold most of them. However, my Mono NF MM will stay with me. It's a very practical bag for shopping or travel. I'm not into speedy until recently and got preloved epi leather one. I also didn't like Alma shape until I see the Alma BB and got one in epi leather as well. Good luck deciding!
