Just wondering what to get, i have a budget of about 200.00 and i'm playing a Martin acoustic 00-18 guitar worth in excess of £2000.00 so would like to have the best sounding thing possible for the money i have available to me... so i'm trying to decide whether to go for an amp like the Marshal AS50R acoustic amp which has built in sounds etc and i can pickup for around 150.00 or a PA system like the one below


I don't know! what do you guys suggest? i would like to use the microphone aswell and i know that both the acoustic amp and PA support Mic etc...

my only worry is with the PA is it likely to give feedback more so than the acoustic amp?
(Any recomendations on PAS or Amps below 200.00 let me know!)
thanks alot
