EXACTLY!
this has been my point for the last 6 months!
i paid for mine to be done, but at least i got peace of mind and a guarantee on the work 
there are some of us who are "talented" with vehicles and some of us that quite simply are not 
I am in no way talented on car mechanics.......upto about 3 years ago every car i had was main delaer serviced

However since this site and a previous one i was a member on......it has given me the confidence to have a go myself on simple jobs.
I pick and choose which to have a go myself.......ie pad changes......not that difficult......i did get lost at one point about the pad sensor but asked on here and was pointed in the right direction

Ive changed the front disks too

I try to research as much as I can before starting a job.......ie check the maintenence guides or post questions

Hardest job i did was the cam cover gasket.......but i got there in the end
Oh and maybe replacing the blower fan.......that took me 6 hours start to finish

Jobs im not confident on are cambelt changes......
Also my exhaust manifold is blowing at the moment......the reason has been identified and the head of engine has to come off......this again im not confident on.....so another member on here is coming to give me hand shortly

And also have a look as to why oil is leaking out faster than im putting it in.......ok its not that bad....im loosing about a litre of oil about every 2k miles

and it is leaking it......you can watch it drip

The reason i started to have a go myself.......my local vx dealer had my omega 8 times trying to fix a hot starting prob and failed too

I took it to TB to have a look with his TECH2, he identified the prob as being cam sensor......and even tho the dealer had told me they had changed it......i paid to have it changed again by a local garage and suprise suprise it fixed the prob

I vowed at that time never to take the omega back to a vx dealer for servicing......
Mind you if i had known then how easy it is to change the cam sensor on a 2.2 i woulda done it myself.
I have been lucky i guess......the local garage i use now and then......let you wander about the workshop and watch the mechanics do the work on your car......so ive learnt watching others and
think sometimes......blimey thats not difficult i can do that myself

So between watching and helpful advice on here im getting more confident

I think the answer is research and take your time

oh and get the correct tools for the job.
I admit my 2.2 is easier to work on than the V6's
Just my 2p worth.......if i can do some jobs then anyone can
