The turnaround is about 3 days now.
The mods can be tailored for the analog outputs instead of the digital. The power supply mods do improve all the analog and video outs, but there is a lot more that can be done to improve the analog outs. However, it is more complicated than the digital mods, so this will probably cost around $800 to do. Op-amp replacement, Decoupling caps, DAC filter and Superclock are some of the things that are possible to improve the analog outs.
