I was just looking at the Halo site.....the kit looks nice...very similar to the Joye 510.(which also comes in a variety of colors)
Halo seems to be a little more expensive than Joye tho......just want you to research...especially if price is a consideration...
		 
		
	 
They do offer a 10% discount to ECF members . . . It is " ECFTEN " (Edited: Changed just looked it up) . . . 
I have the "G6" and IMHO I really like it myself -

  . . . Good feel in the hand and similar to "analog" . . . they also offer "cartos" at a discount price the more you purchase that come in a little pladtic box that is handy & easy to carrt around with you too . . . Just my 

 . . .
Oh - BTW, GREAT Cuxtomer Service too . . . 
 
Edit: P.S. Another piece of info . . . 
As a second choice and back-up . . . I also just order and am awaiting the Volt Pro set (extra "cartos", the "little Coloeful caps", and a couple extra 
batteries - gotta get ready when I find my WOW ! ! ! !) - seeing the really great sale they are having right now with the "Heatwave" 23% off and the newer PCC is included too . . .
