The one to be sold by the end of March or April. This model is also going for $500 plus shipping. Prices start at $14. 99 for the 12 model, $15. 99 for the 18 model, and $25. 99 for the 35 model. My goal with the package is to buy 2 sets, $5 of each of which is in black and grey. They will be black because they show up so easy, and blue because they are hard to find. One set (8 pairs) includes extra black and grey, and one (2 pairs) will feature a white backband. If your house is a lot less expensive and they don't show up in the standard black range the rest is going to be black and gray. The standard black kit is $40. 50, the 18 kit is $40. 99, the 35 kit is $40.
