Ceiling Sepeakers: Polk vs Yamaha vs Monitor

I'm looking for 4 to 6 ceiling speakers for a Kitchen/Lining room area. I'll be hooking these up to some yet to be chosen AV Receiver.

The available options seem limited. My budget isn't massive but I want to avoid the €30 cheap pair type.

I've seen Monitor Audio CT165 for around the £100 mark per speaker on line.
I can get some from the US soon though so I've been looking at BestBuy who have Yamaha NS-IC600 WH for $150 and Polk Audio - RC60i for $130 (both per pair).

I'm leaning towards the Polk ones but I'd love to get peoples opinions as I have limited experience on the HE front..
