I have to concur with most everything everyone has said here so far.
If you'd like to talk to someone who HAS started a nanobrewery with a SABCO system on a part time basis, give the fine folks at "Dirty Bucket" in Woodinville, Washington a call. -They work their day jobs and then have been working non-stop operating the SABCO. They have a cool little retail location to sell beer directly and they get a lot of walk-in traffic being in the middle of Washington's winery tap room town of Woodinville and they gave up on the SABCO in less than a year they were upgrading.
The SABCO also isn't great value if you shop around and compare it to alternatives options.
If you're in a state that allows you to sell directly and you're in a good location where you can sell all of your beer directly, AND you don't have to pay any rent or carrying costs on the facilities that HELPS but it can only help so much. 7bbl has been considered the minimum for small brew pubs for a while, but some folks have survived on smaller systems in recent years. A 1/2 bbl is an exercise in futility, though.
Stout Tanks in Portland now has the basis for a 1 BBL system for $3,100; you'll need pumps, burners, hoses and loads of other things (including more and larger fermenters) but your money will go much further than with the SABCO system.
MANY small (and award winning) breweries in the UK use converted dairy tanks as open fermenters and make their own attemperation coils to keep fermentation temps under control. The UK has really found some models that allow small breweries to survive even in an INSANELY competitive and over-crowded environment but it involves making intelligent decisions in purchasing and adapting equipment; they're not even ATTEMPTING to use US 1/2 BBL systems, either, though.
I'd put 3 BBL at the bare minimum for the brew house if you can sell all your beer directly and don't have any debt or rent to pay. You'll want to maximize the use of all your equipment and make sure that you're double filling or triple filling fermenters (Fermenters should be 2x - 3x the size of your brew length.). -If you invest in water treatment and deaeration/degassing equipment you could also use high gravity brewing techniques to increase your output with a smaller brewhouse. (Example: If you're brewing 3BBL of a 1.050 beer instead brew it to a gravity of 1.075 and ferment it out and then water it down to 4 BBL of 1.050 beer by adding sterilized, treated, and deaerated water on the way to the serving tank. -It won't taste quite the same as if you made a 1.050 gravity beer, though (more esters and higher alcohols).)
So in summary: I agree with most of what everyone else has said already BUT if you're definitely dead-set on doing this don't stick your head in the sand; address the most significant concerns by going with bigger equipment on a similar budget. -Focus on maximizing the amount of beer you can get given the size of the brew house AND still getting the biggest brew house you can for the budget.
(Fermenters are going to cost you and they're also going to be the bottleneck if you even remotely correctly size the brewhouse; there are some US nanos who are using plastic conical fermenters for primary fermentation quite well and very inexpensively and there are some UK breweries who use repurposed stainless dairy tanks; temp control IS important but it's easy to do. -It's as simple as buying a large glycol cooler and pumping either chilled water or chilled glycol through a coper or stainless coil emerged in the beer or wrapping the fermenter in heat transfer coils (some breweries even use plastic for this although the heat transfering properties aren't great.) Also make sure you can sell all of your beer directly or your profit will be completely non-existent (it likely won't be a living in either event).
