Is it worth it for yeast starters to get a stir plate?

Pro's & con's?

Yes. It keeps your yeast continually in suspension, and continually aerated. You get much better growth with a starter than without.

I am not sure what the cons are. Maybe cost, and you need electricity to run it. And you want a vessel with a flat bottom so the stir bar won't get thrown.

I cant think of any cons...since I got my stir plate I have seen faster starts, faster fermentation and better attenuation. Very much worth the investment in my opinion

Thanks all. How much faster can you get a starter to a pitch size? Moderately noob-ish question here. I usually just make 2 cups water an 1/2 cup DME thn pitch a smack pack or dry pack of yeast in growler and wait 24 hours. Pitch entire cake onto wort. Not sure how to determine pitch rates yet. I make mostly (all) ales so I like a nice healthy bunch of yeasties when pitching.
Recently got immersion wort chiller and aeration stone setup. So I was just looking at a stir plate as the next best way to improve my brew taste (I do five gallon boil with propane, I made a fermentation chamber that holds well at 64 degrees).

I am going to try yeast washing and I want to make sure the yeast is viable as possible from starter. I think stir plate is best sol'n.

Here's a nifty little chart of why it's good to have a stir plate.

you get a lot more yeast cells by using a stir plate.

The starter isn't done faster (although maybe it actually is a bit), the fermentation of your 5 gallon wort is what really starts faster. I've been happy with my stir plate although the only real advantage I've seen is that I don't have to manually shake it and the starters are a lot smaller.

I can now make starters for lagers and large gravity beers in my 2L flask without having to step up at all.

Take all the guess work out of yeast pitching by using Mr. Malty

Just look at the difference between stir plate and everything else. In the long run, that translates to money. If you need a particular cell count, it will cost you less DME to get there due to the efficiency increase.

Another 'pro' that nobody mentioned is you don't need to tend to the starter by constantly shaking it for the next 24 hours. You can play Ron Popeil- set it, and forget it!

Mr Malty is very cool. I bought the iPhone app. How do I determine what the growth factor is for a starter?

Again, thanks for the information. This site is a wealth of knowledge.
