buying used board in Bali

Hi guys,
going to Bali with non surfng gf, first time for both of us, we'll spend a total of 16 nights there, first few nights in Seminyak, then Jimbaram, then Ubud, then we dont know yet.
Is there any surfshop you'd recommend in particular to buy a used board? or are they all the same? i bought the Indo SUrf&Lingo book, so there are many advertised surfshops there.
Also, can you find used DIverse surfboards over there?
any tip you feel to share is appreciated! to be honest, I saw the latest swell arrived there, and being a post novice surfer I am a bit scared by those monsters...
thanks a lot in advance!
