Try Stan Cedarleaf Decals - http://1stclass.mylargescale.c...s/CustomDecalsx.html
He uses an Alps printer. His decal sheets are expensive - $30 - but the quality is excellent. He ships in 1/3 sheet segments so he can go with a simple stamp so shipping fees are nothing. However but always order a full sheet. If you order a 1/3 sheet you still pay $30.
PS - I found that using warm to hot distilled water on Stans decals along with those I print out on my computer makes them conform to irregular surfaces right away thus eliminating the need for a decal softening solution.
