Ares guns are very nice, but they have some proprietary parts. This may make upgrades or repairs more difficult in the future.
I see that website has some nice looking G&Ps which may be a better choice in the long run if you can save a bit more money. VFC is also an excellent choice.
G&Gs (Top Tech line) are pretty damn good for the price, so that's worth consideration if you want to save money.
