Hi Mak,
Glad to help!

There are several acoustic bases with alot of brands that I cannot recall, however, I myself was playing some at a music shop the other day and I'm really starting to like their "neck action" and lighter feel about them. I've no doubt they can rock up as well. What I suggest is you look carefully at the craftmanship of the whole body structure and make sure there are no dints or scrathes first.
Secondly, have a close listen to the sound they produce as some are "fatter" than others dues to hollow wood body. I would recommend a lighter sound to medium for busking.
Thirdly, the price! They can range from $300-$800 and the difference in sound is unique although you won't hear it straight away. I'd go for something in the $400-$700 range for longevity and variability to achieve soundscape of different genres to play at a given notice for night club gigs as well. But if economic downturn is affecting you go for the lower price tag
Lastly, treat them with utmost care as they can be very fragile and won't take too many bumps continuosly. The brand I'd look at is "crafter" as I think it's most underated.
cheers
