If it was $225 I would most definitely send it to a shop. From what I see, the only specialty tools I will need would be the mag-base indicator and the rotational torque wrench. Rest of the specialty tools are available via rental at local parts store. On one hand it would be nice to drop it off at a shop and pick it up the next day ready to go, but budget is tight and a little extra experience is always nice.I'd look into the cost of the tools, and also take your time into account... You might never use those tools again, and if you get it wrong even a little it will ruin the gears. That's one of the few jobs I elected to pay someone to do, but I think he only charged me like $225 or so.
