I've used the Bell brake and shifter cable/housing kits when rebuilding older 10/12 speeds. Works great and is inexpensive. ditto for th echains - absolutely no problems.
Also, you can get Crossman 12gr Co2 cartridges there, box of 24 for $12.99. Pretty good deal.
I've also bought both the house brand and Wilson brand base layer undershirts there, and they work great and have not worn out yet after 2 years of hard use. Target has similar shirts, as well.
