there has been a few performer jr's on us ebay but practically all ( out of 8 that i tried for ) had refused to post to england and the one that said he would insisted shipping would be $300 for a frame forks and bars set, so that was a no no as i've imported two frame sets together for under $100 in the past,
finally got one one though, frame & forks + shipping $140 = £75, although one that refused to post to me sold his complete performer jr for $153 so if your after one keep your eyes peeled
