Got Hogtunes speakers for my 09 SG on EBay for $84 (new). Can't beat that deal...J&M are a tad more expensive, but not sure they're better quality. I'm just looking for little better sound than stock & not a loud music fan while riding. Like to hear the road sounds along the way.
I can't remember what the specific warning was about, but the Hogtunes website strongly discourages buying their products on Ebay. Something about warranty returns being reboxed and finding their way back into the market.
