I have had sales enough where I use DigitalOcean VPS for now and I would say they are far from scammy, but the IPFS tech is coming with 2.0 so stores do not have to be online. They update fairly frequently, I would not poo poo it off so quick based on early use. Having been there for 5 months, it is really coming along.
I have been using Etsy for Paypal option with my sales, still haven't put anything up on Peerhub yet, I am trying to find separate items so it's not all the same stock on each store. Either way, good luck in whatever ways you choose to handle transactions, I just figure it is best to have all venues open (it's why I still have an Etsy open, people use CC and Paypal often still, but if they use OpenBazaar or Peerhub, they get better prices). What is your OpenBazaar handle?
