RX8 combos vs MMM combo's

hey guys i have a mmm 2200 and was wondering since alot of people are tlking about these combos,if they were as good if not better than mamba monster.The thing i like about them that i have seen is they have many kv choices and there customer support is great.but the thing i saw that i didn't like was the prices like 330.but i guess what you pay for is what you get.
Thanks.
