My view is that a Suhr will beat a Sadowsky or Fender any day of the week easily.
Yes they lose their value easily, but purely becuaser their not as known, but why would you want to re-sell it? They're great instruments.
I have also done a self build fretless using some Warmoth parts, which are also great. But if your worrying about a Suhr losing value, then you've got a shock when it comes to re-selling a self build which NO ONE has heard of. If you get my drift!
For the money I would go with a Suhr, quality well made guitars that aren't as mass-produced than the Fender Select's. I work in a music shop abnd have seen some of the selects come in at the factory on a rep sales course. - They are sh*t, lol. Not worth the money in my view.
You won't be dissapointed with the Suhr range.
