I now have lots of Harry transponders for trade in. You can trade in your old transponders (AMB and Clones) on a one for one basis for new Harry transponders. So everyone gets a chance to upgrade there is a limit of 5 trade ins per request and it is limited to the UK (via my website). This trade in offer will be available during April and May.
If your old transponders are getting a bit frayed now would be a good time to upgrade to the new RC4 transponder standard.
www.bbkrc.com/harry for the offer.
