The trouble is, getting a HuCard only can be fairly difficult just because complete games are more common.
Super Star Soldier, for example, may be less than 1000 incomplete, but it's most likely going to set you back 1500-2000 complete.
By the way, roflmao, you've got a great list there, but just FYI, the Japanese Bonk HuCards usually aren't so cheap. Complete ones seem to be around 2500-3000 yen. I think it'd be pretty lucky to get the card for 1000 or less.
Anyway, today I picked up P-47 from my local game shop, complete in fairly used condition, for 525 yen. It's decent enough.
