Double sided
PCBs are not much harder, surely?
In fact they're a whole lot easier, at least for the soldering!
If they have plated through holes then they take solder very nicely
(although desoldering can be slightly harder if you need to correct a
mistake :-)). Even without such holes (which means you'll need to solder
some components on both sides of the PCB and maybe put pins through vias,
it's a lot easier to solder such a PCB then fit numerous wire links
