Yes. A DIY spot is good. The big problem is, has the poster performed the fix or is he/she just quoting hear-say?
Also can that person shoot decent photos, and write well enough for me, the DIY to clearly understand and do the job?
Evo does good work and I've read him for about a year. However the NA451 Smarts are a bit different from the Euro models and many of us now look here, and CSC for tech info, as well as Evo's site. Worth thinking about. A2Jack.
