Naxo NX01 Binding

I just got into AT skiing this year and rented a couple of times, I bought a pair of second hand Naxo NX01's off Mec Gearswap still waiting for them to come in but I got them for $100, i'm a total gear head and really try to do my research before buying gear so looking at reviews I saw pretty good reslults at first. Now that the guy shipped them on COD I was looking into mounting them and found a lot of things going wrong and a bunch of complaints. I am worried now that they arn't a good binding I would rather get a better binding for more $$$ and not have problems with it. the biggest thing is I don't want to drill my ski's and put the Quiver killers in and then find out the bindings are crap and have to switch in a 2 years then have to get new ski's. any thoughts on the matter?
