A.C. Questions

[jorgensensc]

I know y'all have seen me post alot recently. This board is addicting I can't seem to get enough information about everything under the sun for our trucks. Everyone on this site is so helpful that I enjoy reading posts about things I don't even need to know about, just so I can pass the info on if someone else ever needs it. Alright, enough of the schmoozing Here is my question:

I'm moving back to the great Country...er...I mean state of Texas in 2 months (stop for cheering in background to die down) after a very long 5 year enlistment in the Marine Corps. I got plenty use to the heat while I was in Iraq, but have since decided life is too short to sweat!!
My options are
1) Buy or put together a factory system and install it before giong back home.
2) Buy or put together a newer model pickups factory a.c. system before I go back home
3)Buy an aftermarket system , but wait until spring before I can afford it.

What do y'all think is the best option in y'alls opinion. I'm really pretty good at making things work, and they usually look good when I do it, but I'm not a machinist. I have an Auto hobby Shop on base tat has about any tool that I don't own. I can't weld, but can have it done pretty cheap.
Thanks for your time, I know it takes time to read posts and help people, but I really do appreciate it!!!
