I would use gbax.com, but they don't have the backlit in stock, nor does lik-sang as far as I know. So if I was ordering a gp32 with backlit now I would order from entware.com
The service from GBAX is great, youll get it before 12 next morning no matter how late you order it (i got mine at 8:30am after ordering at 4:50pm the previous night... hows that for service... saturday too)
but yeah, if you want a light version NOW you need to look elsewhere, GBAX are getting more in May tho, and dont forget any of the other places youll pay a hefty charge when the postie arives at the door
