We use a couple of "stick" choir mics similar to Ace Backstage units. The next time I'm at the church, I'll double check the manufacturer and model number. I've used them for a variety of situations including sections (Usually strings) for when we've had orchestral events at our church. I find them VERY handy for when you want to pick up a wider area of sound (Wedding vows, for example). I've put one in the middle of a quartet and picked up everything quite well. (Note: I'm not making a studio recording as it isn't my goal, but they are just fine for a live recording...)
Another latest favorite are the Rode M5 "Matched pair" of mics. They come in around $200 for the pair of them. So far, I've used them for picking up harp, violin, flute, and guitar. I use a similar one UNDER the grand piano and it gives a nice warm sound without the harshness that most over-hung mics do. You'd ESPECIALLY like this configuration if you have a VERY powerful vocalist at the piano! (Which is why I went under the piano after having such a gentleman at the keys! :-) )
My personal choice is that I like flexibility when it comes to mics. Not everything is 'set in stone' and I may need to move things around. Granted, our stage is set up with pockets so I can minimize or at least hide cord runs, but where your cords go may be an issue.
If you video record your services, ask your camera operator what they think as well. Some mics will stand out like a sore thumb depending on the environment.
Good luck!
