Same here, Benji. A singlespeed hub is great, and offers a bit better triangulation for the spokes, but you lose the flexibility of going back to gears, or moving them on to a geared bike.
One other thing worth bearing in mind: get hubs that are future proof and adaptable. An example: I have a set of Hope Hoops with Crests on. Aside from a QR front (and I’ve got the adapters for that anyway) I’ve used every combination of 135 QR, 135×10, 142×12, 20mm and 15mm. They’ll transfer over to a bike with different axle standards, and have done already. I’ve been shopping for a second set of wheels, and it’s a bit shocking to see that quite a lot of hubs aren’t as future proof as Hope’s.
My recommendation: buy a set of Hope Hoops. I’ve tried (and failed) to spec a self build set of components for the same price in the past.
