We used the tubulin alpha 1 promoter from the Tubulin>CD2>hh construct (Basler & Struhl 1994). I don't know from which tubulin locus it was derived. This was cloned as an EcoRI-KpnI fragment into Casper 4, followed by EGFP (clontech EGFP-N1) as a KpnI-NotI fragment. This construct is described first in Brennecke et al 2003.
