All in all, I'd buy the Springfield and do the mods with whatever pocket money you can come up with.
Skip the "DEAGLE"(as it's nicknamed). So far the history on quality is spotty at best. You can probably find more info on one at one of the bigger generic gun forums like THR or TFL. The kids like buying the newest, latest and greatest, thinking it's like a new TV, with their new is always better mentality and the like.
the Desert Eagle is liked by the kids for the price point, but lot's of flaming about the quality for the most part. But, since it's a true 1911 fixing the issues are not too difficult by buying quality replacement parts from one of the major makers.
I read where there were a couple of slamfires and plenty of FTF/FTE issues related to the mags they supplied.
It appeared that most of the feed issues were resolved when better mags were used.
Forgive me, I'm not a 1911 owner, so I'll probably use the wrong description here, The one kid had to replace his main recoil springs, guide rod and bushing to get the barrel to drop correctly when ejecting after the shot - whatever that means. Until he made all those changes the casing wouldn't eject completely, and sometimes not at all.
At any rate, best of luck.
