I think you never know. When Ibanez released the Afirma as a limited edition it wasn't high priced, but unlike there other limited editions it now fetches more than it cost. Maybe because it was unusual. Ibanez's prestige stuff, made of luxury woods etc devalue quick… You never know. I think something mid-priced, and a little out of character, the kind of thing that might not take off and then disappear soon is a better bet!
Thats one reason I just bought an Ibanez SR2010ASC Ashula. Unusual and a mid-priced limited edition.
