+1 That a used AE212 would be great.
I typically don't play this sort of 'hide and seek' game, but if you wait about 7 days, there will be another great option for you announced that will be on the market by March
If you are on a budget, the GK Neo 12's are quite nice.
Per your question, a high quality 212 or 2 x 112 will give you '410' type volume, and would cover all but the hugest, loudest gigs with no PA support. A 210 is much more limited.
