Personally i'd suggest staying away from the xceleron speedos, i've seen way to many people have problems with them. i know some people will disagree, but its just my opinion
get something like a speed passion/tekin/nosram/LRP or even the Xceed speedo. A fried of mine has been given the xceed to try and said hes very impressed with it considering how cheap it is!
Other than that it all sounds good, i can certainly say the orion is good charger, nice and simple and reliable
