Well, even coming from somebody running three LMT BCG's...
I'd get the DelTon with the BCG included. It'll run, and they're quality units. You'll hav to check over the carrier staking if you plan on shooting it large amounts (see QUIB's guide), but it'll be a good value since you're getting it with the upper.
Still, if $130 is out of your budget, consider ammo prices to actually keep it running, and at what point you'd end up buying another/spare one to replace it. If you're not shooting tonsof rounds through it, then the included DTI carrier group will run through thousands of rounds over the course of a decade without a hitch. If you see yourself going to carbine courses, rapid fire shooting, or other high-volume training, then a BCM or LMT would be worth the added investment.
Lowers can be readily and easily built, assembled, headspaced uppers are still a good value, and cheaper for somebody with stage one BRD who can't afford to sink lots of money into appropriate tools.
For your budget, the DTI complete upper makes sense, go with that.
