'Mex Fenders are the lousiest in the fender range'- this is what our fathers before us would say but because we're not privy to such an era, we'd do well to check out today's mex offerings & decide for ourselves. i'd say that some mex models are superb & absolutely value for money instruments. a good start would be to check out the Classic series (re-issue 50s/ 60s/ 70s models), as these are fantastic instruments in terms of construction & tone.
'Jap fenders are definitely better than mex'- a snob statement which carries questionable value. after Y2K, wood-wise, mex fenders are alder, this is an applaudable move as it keeps to the true tone of Fender. not all jap fenders are alder, some are basswood but do not dismiss basswood just yet (many would equate basswood with junk), it might appeal to you instead of alder.
keep your options open because between the mex & jap price brackets are the american Highway1 models which are very under-rated here. why? because people here go for looks & specualtive quality, which the H1 models fell victim to.
