What mikrotik and what mini-pci card is best for client???

Hi, I am using for clients as wifi ovislink 5460 and WA2204, but I have some problems with them. I would like to buy some mikrotik + mini-pci wifi card, could you help me what are best for client?
For 2.4Ghz, I am thinking of CM9, R52 or some compex card or what do you recommend?
Of Mikrotik I am thinking of this: rb133, rb411, rb150?

r52s all the way

We found that RB411 is perfact as a CPE. You can use R52 or R52H.

Thanks for answers, what adapter is best to use with rb411+r52? 15V, 24V, 28V, 48V?

18-24V
