A little piece of advice.... about 30 years ago I too fell under the spell of the 12 string. Bleeding pain to tune at first, but sweet sounding with flatpicking. Surely no room in there for my fat fingers, as in those days I was deep in persuit of "classical" skills.
Anyway the less expensive 12s out there are often a bit weak in the internal bracing department, and with the additional tension of those extra 6 strings are prone to "saddle lifting". Naturally this results in way WAY too much fret clearance and a bowed top downstream of the saddle. Try tuning down a full note and capo back up to reduce tension. If it warps you might find (as I did) that the repair costs can be more than the initial cost of the instrument.
