electric eel d-5 vs rigid k750

Ok so im thinking about upgrading from my model R to something with autofeed that can go past 100FT. Which would be the wiser choice the D-5 or the K 750 the electric eel d-5 is about $200 more than what i can get a new K-750 for but i trust the electric eel cable to be sturdy and on rigids website the k 750 had bad reviews and several of them said the cable had snapped ! any help would be appreciated !Has anyone ever ran either of these machines in the field for long periods of time?
