I use 4 LBKs on a regular basis (sometimes 6), and have a few

more. If you're considering getting more LBKs,
I would recommend you wait until the January/February timeframe when the stores put them on clearance. For me the size is perfect - I make 5 gallon batches but don't want to carry 5 gallons due to a bad back. And my upright freezer with coils under the shelves perfectly fits LBKs and nothing else - I could have 5-6 in there at once.
In January 2013 I bought 2 full kits from Rite Aid for $12.49 each (sold one for $30 and the other for $25 before deciding I wanted more than my initial 2).
Last year Mr. Beer made special packages just for Target consisting of an LBK, a can of CAL, carbonation drops, and no rinse sanitizer. I bought 5 of them for $8.98 each. I then sold the cans of CAL (I don't like it) to a fellow homebrewer, gave them a deal, ended up costing me nothing for the LBKs. I also picked up another LBK and ten 25 oz bottles, plus another can of CAL and a can of Irish Stout, for $10 on Craigslist, have the can of CAL again for sale.
So that's 2 original LBKs (I from Woot, one from CL), 5 more from Target, and another from CL for a total of 8. I also have 2 others that were replacements for ones with defective holes, I ended up using a file and got them so they wouldn't leak - so with 2 more spigots and 2 more lids I'd have 10. I only really have a need for 6 max - my youngest son (who moved back home after grad school but professes to want to brew when he goes on his own) may take 2 or 4 with him.
So I'd say wait. Get the list of local retailers from Mr. Beer's site in your area (usually Target, KMart) and search online come mid January.
Also - Mr. Beer just changed the LBK to a bigger opening and a black spigot. Some other things going on - I expect large clearance sales coming up in January.
I have over 9,000 posts on "another forum", which means absolutely nothing. Mr. Beer January 2014 Brewer of the Month with all the pomp and circumstance that comes with it...
