If you can, it would be best to bring your main acoustic guitar when you test amps in a store, you can then easily pick out which one responds well with your playing and your instrument. My best bet among your selection would be the Roland AC90, although you will have to extend your budget a bit, you will find that its versatility and sound (especially its mic input) - is worth the extra cost. Fishman Loudbox would also be a great choice - specially since your guitar has Fishman pickups, plus you get to save some money for whatever else you need.

Good luck!
