That's a very good approach! You should add a second WiFi interface to
your laptop, so that you can see with one interface what you're doing
with the other.
You could look for USB sticks that in this table  have both
"cfg80211" and "AP" marked with "yes"; it's probably easiest to find a
USB Wifi adapter with ath9k_htc chipset , or the rt2500 or rt2800
chipset (tend to be cheaper); note that these lists are not comprehensive.
