I had mine restored for about $140-$160 a pop for the big gauges, and $120-$130 for the little ones. You can buy a restorable condition gauge off of ebay for 20-30 bucks if you don't have one yourself. Restoration was a veeeerrry sloooow process, however, so be warned. Regardless, cheaper than the $200 range I quickly glanced at on that one link for new gauges, plus you will have an original gauge (btw, my personal definition--everyone's is different--for original is 1) is it the "correct style" item for that year/model and 2) when the item in question was originally manufactured. Restoration of "correct style" gauges counts as original. Some purists would have a heartattack, I know)
