I went with these from Lockhart Phillips:
3.5in x 2.25in Flush Mount I Dual Filament Black/Smoke 1229693 $14.95
They cover up the stock turn signal holes on my 1g and look great. Only thing is, you have to drill holes in the fairing to mount them since there isn't enough plastic showing around the hole to use double sided tape.
Heres a pic with them on the bike. Can't see em all that well in the pic.
