Repeater that'll work with Microsoft MN-700?

>From what I gather, getting a repeater to work with a router/wifi
access point is a bit chipset based, correct? Anyone set something up
with a Microsoft MN-700? I'm looking for a repeater with dual removable
external antennas so that one can be replaced with a directional
antenna, so that rules out just using another MN-700 in repeater mode.

Thanks!

Also, I should add, if I can't find a repeater that'll play nicely with
the MN-700, any suggestions for what manufacturer makes a good repeater
friendly replacement? Is there a really good access point/repeater pair
that's better than the competition? I wouldn't be opposed to a higher
powered access point that might either eliminate the need for a
repeater, or at least the need for a dual antenna repeater using a
directional antenna for one of the antennas (I think SMC is one of the
companies that makes a higher powered unit). That being said, first &
foremost, if I do replace the access point, I want one that's done
right - I hate it when I buy something just to find out there's a bug
in the unpnp, or that there's some other stupidity either in lack of /
or poor design of features. For example, given the price competition
for access points they're many times cheaper than a simple repeater,
yet some access point makers don't design the ability to configure it
as a repeater.
