Don't know if it's a bit far for you, but there is a barn near Ballycullane in Wexford that had some great stuff at reasonable prices when we were over last year.
Can't remember the name of the place, but if you go along the R733 from Wellington Bridge towards Duncannon you will see a sign on the right hand side to Somer's Fort Cottages and to a Florist. If you take that turn and then the first turn on the left you will see the place on the right hand side. Alternatively, continue on the R733 to the junction with the R734 towards New Ross and take the first turn on the right. (This turn can be difficult to see.) That will put you on the same road as before with the place on the left hand side.
Good Luck
