RM-X4S and RM-X2S remotes

Hey,

I thought I'd start this to have people post the cheapest place to get these wired remotes. Also, is one clearly better than the other? Whats the difference?

Thanks,

John

You'll find plenty of on-line sellers just be searching on RM-X4S. Crutchfield carries it; great service but perhaps not the best price. SoundDomain.com had it for $30 U.S.D. My understanding was that the X4S superceded the X2S model (I could be wrong).
