Not worth it unless you plan to keep it for life or acquired the parts a long time ago when they were reasonable. To hard to sell if you decide you want a change. Lost my *** on every single build. Even when you know the market and acquire parts at fair prices, it is just to hard to recoup.
One build I spent 8k on and sold it for 6. Would have made more back if I parted it out, but did not want to tear down a project that took a year to put together.
I really appreciate the guys who can take stock reps and modify them to look good but for a reasonable budget. As I improve my watch modding skills this is a really fun part of the hobby and one that makes more economical sense.
Pretty much done doing high end builds. They are fun to do but generally illogical. This is why I switched to collecting vintage gens instead. At least I know they will continue to increase in value and if I decide I want something different gens are much easier to move. And at the end of the day, a gen is a gen, especially vintage.
