Ok, excited rambling about holiday to follow, feel free to ignore: Egypt!!

Ok. So I looked up the tour we're going on in Egypt (because I'm bored and procrastinating, ok?), and now I'm actually excited about it because it finally feels like it's going to happen. I haven't really been that excited yet for some reason. It doesn't seem like a real thing. I guess because for most of it I don't have a clear idea of where we're going in Europe. BUT, EGYPT:

( Cut for boring list )

So yeah. Things. One of these days I'll upload my underwater photos from February.

So I was thinking I might buy a secondhand Digital SLR for the trip. But I'm torn. They are a lot of money, and I will need a lot of money to last me for over 6 months of souveneiring, even without accomodation and food. I don't know how cheaply I could get one worth having, but I'm willing to bet I wouldn't get one that works for under $600, and think of all the things I could use that $500 on!
BUT ON THE OTHER HAND
I am going to amazing places. I'd like a camera that can actually do them justice. My camera can take nice photos but I want awesome photos. I guess I could buy prints or postcards but I don't really want to do that, I'd rather have my own pictures of my own memories. I can get photos of the pyramids from a store here, for example. So it's a tricky situation.

What do you guys think?

[] Do it
[] Don't do it
[] Ticky

OK SO I DON'T HAVE A PAID ACCOUNT AND CAN'T REMEMBER THE HTML FOR TICKY BOX. :'( :'(

Oh also I don't currently have a thousand dollars. So I'd need to sell something/get money and therefore have EVEN LESS money for the trip. My concern is that if I buy a swanky camera I will be even more of a terrible leach-girlfriend-who-is-making-boyfriend-pay-for-everything because I'll run out of money even sooner.

BUT on the other hand maybe I won't want to buy as many things because maybe I'll be super happy with all my awesome photos? 
 

GOD.

Oh yeah and the other thing is my Dad was going to buy my laptop from me so I can have more money (and then when I get back I can "borrow" it until I can buy a new laptop. My parent's don't have a mortgage any more (yay for them!) and it makes them do somewhat crazy things.
So it's a :
2.4 Ghz Dual Core processor, Intel or Pentium or whatever tf they are calling themselves these days
Vista Home Premium
250GB HDD
4GB RAM
Nvidia GeForce 8600 gfx caard
It's green
15.4" monitor
It's a Deeeeelll.
er, it's from 2007.

If I ask him to give me $1000 for it, is that ridiculous? I mean I know I'm selling it to my Dad essentially for lols and all, and that Dads always pay too much when buying stuff from their kids, but is it TOO too much? It's suffered no structural damage.
 

YES, I do worry too much.

Errrrrgh.
