I suggest snagging a u7 pro for 189 they are in stock.
but if wanting to go cheap the U6 plus for $129 isnt bad.
my u6 lite(s) which are slower than the U6 plus support 500MBit+ speeds.
but you would benefit in a house from a U6LR $179 or U7 pro $189
The u7 pro also has 6ghz (which is of limited benefit)
