Is work your only concern regarding location? IE - What are you lifestyle preference - close to the sea, access to school, etc?
Heres some quick comments...
We've just bought in Wicklow and think it's beautiful there. It really is the Garden of Island and plenty of walking and scenery to be done if you like that. It's not too far from Dublin at all and only takes us 40 mins in the car if we need to visit Dublin for some retain Therapy. Wicklow has lots of great coastline too.
My folks swear by Co Wexford and it definitely is the "Sunny south east" with some gorgeous warmer summers down around Rosslaer etc Houses tend to be not badly priced at all. I personally am not mad on the County itself (sorry wexfordonians!!)
