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 [1] have both "cfg80211" and "AP" marked with "yes"; it's probably easiest to find a USB Wifi adapter with ath9k_htc chipset [2], or the rt2500 or rt2800 chipset (tend to be cheaper); note that these lists are not comprehensive.
