Those pin strips are really nice for that. If you actually need a ground plane for an analog design under it you can always mount a foil sheet under it. They're also breakaway so you can make dip basings for any size using a single generic cheap part you buy in bulk. Mike, where'd you get those from? I don't feel like hunting through my Digikey catalog to find what they are, don't need em now but it's such a 'smart part' for hobby usage I might throw some on my next order to beat the shipping limit.
