i have capped 20EZs, GO-7's, K7000's, K7500's, K4900's, K4600's, K6100's, V2000's, Sharps, Matsushitas, Korteks, Neotecs, Nanaos, Hantarexes... at least 50 monitors in the last dozen years. not a single one needed a recap after only a year or two. in fact, not a single one has needed a recap while i've owned it, and many i've had for 5-10 years (i don't churn my collection like i used to.) at least 20 have been in an arcade and on for significant hours, more than any home collector is ever likely to use it for.
i'm not saying there might not be an advantage to using a higher quality cap and they might last another 30 years (unlike most of us.) but in my experience this doom and gloom scenario of lesser-rated caps lasting only short periods of time just isn't real likely.
