The repeater guides will give frequencies and locations, but the OP asked which ones would be popular. That information won't be found in any of the references suggested so far.
For Rochester, I would recommend the RRRA Megaplex, whose 2m port is on 146.880 and I think the CTCSS is 110.9.
There is also a wide area repeater in Attica (between and south of Rochester and Buffalo) on 145.310. I can't think of the tone offhand, but for that one of the above-mentioned guides would come in handy.
