Personally I have yet to break a mechbox. My AEG's run under 400fps...I rarely play in the really cold (and I tend to run a V3 if it's nippy out). Recently, my main go-to field gun is a v3...and I haven't heard/seen many of those break. I've had plenty of V2's and haven't broken one yet.
For the amount of tooling work that goes into machining a mechbox out of 7075...it's a fair price. Especially landed and just a local e-mail away.
There's some guys who will pay anything to try the trickest/strongest/best parts...and so it may be worth it to them.
Ajax (fixed) custom's makes a V2 saver...they're supposedly running up to 700+fps without breakage. Those only cost $40 if you can get one.
