Slash 4x4 PE Roller Anyone?

[mambarustler]

Im thinking of selling my CRT.5 roller and my Slash as a roller. So I can buy a 4x4 PE roller. I want everything it comes with except for the BL system. Am planning on throwing my Medusa 3300kv and MM esc with the 3PM 2.4ghz in it. Should I go for it? If I buy the PE how much can I get if I sell the traxxas BL Sytem w/ no use? OR should I find someone selling the 4x4 PE without the BL system ?
