I have been looking at cordless set/upgrade exist. I was looking at the purchase of a Bosch set at the Blue Borg. It has the Blue Core batteries. Has anyone had any experience with them? they have them priced at $399 w/ a mail in $150 Store card. That is not a bad price at all! Currently I have a Ryobi 18v set and the other option would be to get the Lithium ion upgrade pack. I have been satisfied with the Drill and impact, but find that the recip saw and the circ saw dont last too long b4 having to swap batteries out. It has been a pain. i can get the upgrade kit for 117 for the charger and one battery...any thoughts or opinions? i am leaning toward the Bosch, b/c they are definately heavier grade...the circ saw is definately alot more like my corded models...if anyone has the blue core batteries, i just wondered how they compare to regular NiCad...Thanks!
