Hi Frank, i think the Ebay link was a one off so no, sorry.
Yes he does make 2 eared and octagonal tools and he states that if they break or fail within 2 years he will replace. I paid £49.99 and he apologised for the price!
Worth an email enquiry i reckon. BTW. you may find a shorter breaker bar works but i figured the longer the bar the easier i would be to use, telescopic bars could be useful if you wanted to carry the tool (instead of a hammer) and keep under or beside a seat.
