LOL, well I have lost all confidence in purchasing this unit. Too bad for me I missed the early registration and pre-orders haha, shitty end of the deal. Looks like Ill be waiting until the new units are available....
During the Plus days, the contract manufacturer was apparently sabotaging units or something to that effect. The story isn't totally clear as they're keeping things under wraps for legal reasons. If you get a "good" Plus, if should be fine for ages, but personally I wouldnt risk it, because as has already been said, VXL aren't repairing them at the moment (none of certain custom parts in stock, and long order times on those).
On the other hand, VXL have now brought manufacturing fully in-house, and switched internals to use more off-the-shelf parts, so they can completely avoid that shit in future. Just hold out another month or two and buy with confidence.
(Isn't there also supposed to be a secondary pre-order thing starting soon/already started, though? You missed the IndieGoGo thing but I think you can still get a good, if slightly lower, discount by pre-ordering an EVO from the VXL site?)
