I have heard of Magefesa before, they are a good company. I like the handle on that model, but if storage is an issue it might get in your way. The Presto model (the Presto links to the Magefesa btw) only cooks at 15 psi which can be annoying. It's like having a car that only goes 0 or 100. I can't see from the information on Amazon if the Concord has multiple pressure setting. I would probably go with the Magefesa model since it has the handle and can be used at low, medium and high pressure.

You might consider the Fagor 8-Quart Stainless-Steel Pressure Cooker. It is $100 on Amazon but comes with a handy steamer basket.
