i bought a generation 1 a couple o years ago,but its crap,i tried it once and its been in the box ever since,i keep meaning to put it on ebay,if you get a generation 3 ,this will be ok i think,i havnt seen one,but they were 1000 a touch a couple o years back,the one i got was about 200-300,and i was most disapointed,i strongly advise you not to jump straight in and get one(which obviously you arnt doing as your asking for advise) some of the lads may have had better experiences with them,im sure they will share them,
good hunting SkinnyRat
