It all depends on what you want from your neck. Pit Bull St**t/T*le ones seem to be fine, but you get the generic modern-C neck shape,a 12" radius and a headstock you have to shape yourself. This may be fine, but if you are looking for a more vintage style Fender neck, with a thicker neck shape and a 7.25" or 9.5" radius and thin frets. then you have to look elsewhere, or build your own.
The PBG necks don't use the best maple. It's certainly not not quarter-sawn and straight-grained. There are occasional small knots to be seen. The fret-ends are generally quite rough and many need a fret-dress to get a low action on them.
I don't know what a $290 neck will be like from the description in that link. It may have been pre-levelled and the fret ends dressed properly. I would expect this on an already lacquered neck, but unless they say so, there are no guarantees. I expect each one will be slightly different and ideally you'd be able to be shown a selection and pick the one that feels best to you. But that's not going to happen.
From the CITES mention. I assume you'd like a rosewood board. Maple wasn't affected by the last lot of changes.
Found this lot who seem to do cheaper necks than ALS. No finish - which explains a fair bit of the price difference as it all takes time - and time is money. But apart from the pre-shaped headstocks, they don't look all that different to the PiutBull necks (apart from having real rosewood boards).
