I've pretty much narrowed it down to the Unibrau and Clawhammer. I like the design of the Unibrau but don't really want to spend the additional $400. I'm not in a rush so will probably wait until holiday time to see if there are any sales.
Here are a few of my thoughts--take them as data that may or may not be important to you in your situation and context.
The clawhammer is the most complete system. It includes a plate chiller, pump, and hoses. A plus is the quick disconnects. I have camlocks on my system because the QDs are just so much more expensive, but they're easier to use. I wish I had them. Nothing that a few hundred dollars wouldn't be able to correct in my case.
I have an aversion to all-in-one systems. That's probably a personal problem
I'd also suggest this: what are you going to wish you had done in six months or a year from now? Are you going to sink money into equipment or an approach you'll regret? Sometimes it might be better to accumulate more money (sell some unused equipment, do some craigslist dumping, give up your lattes for a month or two) in order to get what you want instead of a compromise system you'll regret before long.
Regardless, good luck--fun to have these kinds of problems.
