OP I believe you have been able to go through the posts here by reputable members and I must say all they have said here are very much accurate and I see some links here provided so you could further as k questions or see for yourself where you can get mixers but you will have to do your own diligence for the mixers that best suits your requirements.

I would also advise you to do away with the thought of mixers here as it has already been  banned my the administrator of the platform earlier mentioned members here.
