The nikko tuners run the gammut from amazing (gamma 1) to forgettable.
Iirc the silver line wasn't quite as good as the rack mounts. I'd not pay much unseen, but I'm a fan of the nikko sound so I'd say see if you can test it out.
If it pulls in the station you want, and it sounds good to you, then enjoy. The nikkos do allow you to tune pretty finely (no opinion on how well), 0.5 vs the usual 2.
Personally I won't pay more than $10 for an unknown, even working tuner. There's just no demand. The good tuners are well known and you'll pay well for them.
