[ausev] Manual Transmission Rebuild

So I pulled the MR2 transmission last weekend and set it off to a 
transmission shop up here in Austin.  They do not even have the tools to 
open it, and they don't have the time to haul it to a shop that 
specializes in manual transmissions.  They asked me to come get it, and 
gave me the name of the company (Pistole, in South Austin) that they 
would usually sub the work out to.

The transmission has two problems, a bad 3rd gear syncro (much needed) 
and a metallic rattle that sounds like some loose piece is falling to 
the bottom of the transmission whenever the vehicle comes to a halt.

So now I have a choice, do I haul the tranny to the South end of town 
and pay for a rebuild, or do I do the rebuild myself.

1. I never even opened a transmission before, and the diagrams make it 
look tremendously complex inside.
2. I lack all of the tools required, (including a inch/lb accurate 
torque wrench and a bearing press) as well as several special service tools.

OTOH,
1. I may save a little money now, and certainly will save money if I 
ever have to do this again
2. I can modify the transmission for a electronic speed sensor, and 
maybe even remove unneeded gears like first.
3. The factory manual I have covers the entire process, and is very 
complete.

Thoughts?  Anyone ever done this before?
