My thoughts here:
1. Modern budget mountain bikes are significantly better than older bikes. This isn't necessarily true in road bikes but the technology in mountain bikes has advanced rapidly over the past 20 years, particularly in tires and suspension.
2. BikesDirect is a bit hit and miss. I own several of their bikes and I will say that their frame quality is generally surprisingly high. However you have to know exactly what you're looking at when you're looking at BD. In general, BD works great if you know exactly what size you want and you study the spec sheet thoroughly. If you're really careful, they offer some models that are genuine steals. If not, a bike from a shop is a better idea even if it's significantly more expensive.
3. In my opinion, 29ers are too much unless you're over 6'. I think 27.5" wheels are the best current option. This is just my preference though, hardly "fact". Good luck finding a 26er these days.
4. Plus bikes (basically 3" + tires) can be an interesting option. I'm a believer in the additional grip and float they provide.
5. I agree an aluminum hardtail is the best option if you're staying budget.
6. Learn about tubeless tires. Tubeless is great for mountain bikes.
7. Modern pinned flat pedals are great. I would try them before trying a clipless option. The VP Vice pedal is great and inexpensive.
8. I much prefer hydraulic disc brakes to mechanical disc brakes. They're worth the slight extra expense. Hydros offer much better modulation and they self center.
9. Thru axles are a basic requirement for me. They make it easier to remount wheels with disc brakes, are much stronger and stiffen up the frame and fork.
10. Avoid press fit bottom brackets. They are of the devil.
