For handheld pruners, I like my Felcos too, but only because ANY replacement parts are so readily available. Note that the standard Felco (#2, I believe) has a riveted blade. You need to set new rivets when you replace it. There is an almost identical model in which the blade screws in.
One brand I haven't seen mentioned, that is Stihl. They make all sorts of pruners too, and all carry a lifetime warranty. I don't have any handheld size ones, but I have the seven foot long PP-100:

Because of the leverage within the mechanism, you can really cut some serious branches with these.
But, when it comes to roses, these are my absolute favorites:

Probably not so good for a florist, but I prune my roses outside, and this lets me reach anything, without worrying about thorns.
