I'm mostly GPU and branched into a few ASICs for altcoins but mirror your sentiment; I regret every ASIC purchase I made. They may work but only for the lowest of the low electicity and at which point you'd benefit just as much from adding more GPU's which have a higher security on your investment in resale value as you mentioned (some ASICs turn out to be bricks within a month as I found out. That or hashboards just die.)
