The big question Jimmy, is the new raider as good as the one which you loved so much. If it is, then you know what you would be buying and know that it compared with your HW100 so the decision is not so big, both will work for you, it is just a case of which do you prefer. I think I would be a little nervous getting rid of the HW in case the Raider is not quite as you remembered it.
The ideal situation is to get the Raider and try it out, if okay, sell the HW.
