As anther alternative, I use these MTH distribution blocks and attach wires using crimp terminals. They are a little bit more expensive (although generic versions can be found on the internet for less money), but I find them to be extremely convenient and less of a hassle to use.
They also come in both 12 terminal and 24 terminal versions and can be used for both accessory distribution and track power distribution.
I have also daisy-chained two of these together for accessory usage (i.e., using the last terminal port on one block to connect to the main red and black input connections on a new block) with no adverse results.
