Good luck with that!
Don't forget you need to purge the system, put vacuum to the system and include oil (the correct amount) with your refrigerant.
A/C techs make good money for a reason. My Dad was an ASE A/C specialist. I am very well inclined (mechanically). I'm also an engineer and I still won't do my own A/C work (after trying what you're talking about doing).
I bet this "cheaper route" will cost you more than just having it done right in the first place........Then you'll still have to pay more to get it done right after that!
Here (The cheapest gauges I could find):
CPS Products MB234, Black Max Dual Brass AC Manifold for R-12 and R-134a - DJV Merchandise.com
You'll have to buy refrigerant at Wal-Mart/Parts store.
G/L! Keep us posted.
That's just my opinion though. You may do a great job.....but like I said: Good luck!

I used to work for Mazda's R&D center here in CA, mainly on their A/C systms, which at that time had parts that were sourced from a company in Texas. When using the vacuum pump, its recommended to keep running it for a while after the pressure reaches the lowest it can go, because then any water trapped in the dryer will "boil" into vapor and be purged out.

Looks like I may be getting my hands on a set of gauges and a pump so I'll post back here with the results.
Thanks for the tip Turbo, I'll be sure to let it run for a while.

FINALLY got around to doing this...
To put this simply, I bought (or should I say, WAS bought - it was a late b-day present) a vacuum pump and gauge set from amazon for ~$200. I then bought 2 cans of R134a and followed this video nearly exactly... And it worked perfectly! I now have cold air when before I had nothing!
There were a few small issues in that I didn't have one part of the a/c line screwed correctly into the car so I was vacuuming the line which was just pulling from the outside. It took about 10 minutes of vacuuming to realize nothing was happening... Got that working and everything went smoothly after that. Granted I started from empty so I knew exactly how much to put in (from the manual, or the sticker inside the hood), and all I had to do was vacuum it, then put R134a in.
So, if anybody in the Seattle area has an empty A/C line, I can come help with my set. Just buy the right amount of coolant and hit me up.
