We started letting her practice with them at 6 months old in the bath. At 9 months, she got a sippy of water with every meal. By 12 months, we ditched bottles completely. I wanted to transition by a year because I have heard the transition is harder once they are older and a bottle becomes a comfort measure.
I think we first gave her one at 8 months or so? It was after she'd been sitting up for awhile. We liked the NUBY brand with the handles to start, and have different styles from them now. She likes the soft tip vs. the harder plastic ones.
Introduced at 6 months, switched 100% at a year and never looked back. DS is so unconcerned of which kind of sippy. We use this kind from Gerber, we started with the handles and now use the bigger with no handles. We introduced the straw kind at about 14 months so he could get used to a straw and now we just use a real cup.

We gave him one at 6ish months just to hold and get used to. He pretty much skipped holding bottles on his own and went straight to sippy cups. Highly recommend not creating a bottle habit since everyone I know has had some kind of issue getting rid of bottles in one form or another. DS likes the straw kind - Munchkin are our favorite.

I think we gave him one to play with at 6 or7 months - took the valve out and put water in so he could understand how tipping a cup made the water come out.
It took a while before he would drink very much from one. And it took a while to find sippies that didn't LEAK. I hate sippy cups. The Gerber insulated ones that look a lot like that link above but are taller are the ones that seem to leak the least here.
