Yeah this is totally true Anybody who thinks custom CPC's will resell for anything close to retail price is mistaken Half is about right And that's just because CPC inlays are so easy to pop offAs a long time custom chipper, I will tell you that generally, customized chips do NOT have great resale value (hall of fame or not). You would be lucky to get 1/2 of the original cost. There are very few second hand customs out there that I would justify paying the same amount as a new custom purchase from CPC.
with that said customs are awesome and I would recommend that route if you can afford it. If you are afraid that your taste will change (and they mostlikely will) with time then go for a simple, classic design. Perhaps some solid customs at CPC , followed with add ons in the future when you have additional funds.
