A budget of $1000 won't do it for most systems. That might get you a cart only US VB collection. Maybe a set of 32X games? Looking at your list, here's what I think:
PS2: This would be a massive undertaking. At almost 2000 games, even buying in bulk will be pricey. A few games are becoming quite expensive, like the ones mentioned. I would not be surprised to hear a full set here to be north of $15K.
GC: Much more managable, but games like Phantasy Star Online 1&2 Plus and NCAA College Basketball 2K3 can blow a budget if you're not careful. The library is notably smaller, though, and I'd guess can be done for about $6-7K.
DC: You know the stories- people sell off US copies to get JP copies, and make a mint. (Example 1: Mars Matrix.) But opening the door to imports also blows up the library, and opens the door on hunting down the rare and almost as expensive JP games. (Battle Garega, anyone?) I might peg this in the $7-8K range.
PSP: Summon Night 5 and Class of Heroes 2 will be your rares here for a US retail set, but both are still easy to get sub-$100. A few imports crack this number, as do some complete limited editions. Non-retail gets you some very rare (and presumedly expensive) oddities, like a Hilton training program on UMD. There are quite a few games nonetheless, and I'd guess this set to be $5-6K, but I'd expect this one to appreciate moreso than most others you mention.
N64: As someone working on this, I can say it's not too bad. There are only a handful over $100, and with just under 300 games, an end that's not a pipe dream. A US cart set would be $3-4K.
XB: This seems to be the hidden gem, but not for much longer, I think. Jurassic Park Operation Genesis seems to be the high one, and is starting to push $100. Even at 900 US games, I'd guess a set to still be a tad under $9K. Like PSP, I see this one going up.
Another system for consideration could be the Game Gear. Only a few games have jumped for this, and with a US library smaller than the N64, this might be doable for about $2000-2500.
-I swear, if I ever open a used game store...
