Re: BGE worth the $
We've used ours for approximately 16-18 months, pretty regularly. Not our only diapers, but they received the bulk of the use. SOme of them are more worn than others, but nearly all of them have the fabric tears people complain about, and many of the leg elastics are stretched out quite a bit.
Definitely wouldn't get 2 kids worth out of them, but I should expect that considering everything gets washed all the time.
Fwiw, my Flip covers also have loose elastic at the legs, and some of the butterfly tabs are more stretched out than others.
Can't fairly compare it to my Simplex v2s because those haven't been in the rotation nearly as long, however, 1 of them busted a snap, and another has come unstitched slightly in the back. Nothing major, though.
