For $200 I think I'd dissassemble em myself with 2 clamps & have the main leaf rearched or just add some leafs as is but 2 bills ain't terribly out of line. No exp how long they last & they may very well last forever. All I can add is I bought a 74 duster from a guy in Iowa who used it to haul blocks etc across country to swap meets & it had at least 8 added leafs per side (I ain't kidding) & it was several inches above normal height & every time I hit a pebble my head hit the dome light so they had to go (I still have em). Not sure if he rearched just the main leaf or some of the leafs or no rearching & just added em (my guess he just added leafs)
