Ok now I am confused. is this one of those thing where every one has an opinion and everone is right, it's more of a personal choice?????I realy need an old time gear head on this one that has done both so he can give me the pros and cons of each. But I muss say you guys are realy giving me some good info to base my decision on . So who has what and what do thay think of it???? 4 link looks as if you could realy make a mess of it if you did not know what you where doing.
