Catching situation good or weak?

The Arizona Diamondbacks are most likely going to dump Johnny Estrada. Who apparently had a bit of an argument with some of the dbacks coaches. Well what are we left with? Well some people would argue that we have a pretty good catcher in Chris Snyder, well he may have had a fair season batting .277 and hitting 6 homers in 184 at- bats, but remember what happened last time we left the fate of our catching role up to Chris Snyder. 2005 ring any bells? And some other people would argue, well we have Miguel Montero, well other than he has only had 16 major league at bats and is very in expierenced, should we leave the fate of the very important catcher's role up to these guys? Maybe we should go get a veterin guy instead of these guys.
