Yeah, do like i did, sell your bigmaxx and 18.97 and get the 9920 and the 7 or 8 XL (the 8 XL can run on 20 cells as well)
If you like a blue can, get the wanderer 20 8XL (it is the feigao, only different bearing, blue in colour and it has got the plugs soldered on allready)
Have you seen
this? I am not the biggest fan of schulze anymore.. (one of them was my own 18.97)
