A couple things I would do differently, based on my experience:
- Go with the STC-2000. $20 on ebay. I have two of them now and they work great and are easy to install.
- If you can afford it, spend the extra money and get Perlick 525 faucets and stainless shanks. I think that most people who have a keezer for a while end up being happier with stainless faucets and that much happier again with the Perlicks.
- You can always go with a larger freezer now and add more kegs/taps as you can afford to. You will probably find that two taps isn't enough and you'll want to upgrade. If you get a bigger freezer, upgrading is as simple as buying a keg and the hardware. If you start with a smaller freezer and can't add any kegs in the future, upgrading becomes a lot more expensive.
- Don't buy a new freezer. Check craigslist. Ask friends. My last freezer came out of my buddy's garage and cost me $60 and a case of homebrew.
Do those kegs come with new poppets and o-rings? If not, you will want to replace them.
To answer your questions:
- I would. It's cheap and sure won't hurt.
- Mine's inside. My freezer came with a separator for items in the compressor hump area and it lives there.
- I would have to see pics of the women first.
