I don't know if there is much interest in them but heard several people say they're not readily available in the UK.
A friend of mine is selling 0.0.3 R. Sarasinorum CB 2007 (several months old don't know the exact hatch date but can ask)
so if theyre really pretty hard to find you now have another oppurtunity to acquire some

if interested you can send me a pm and they can be picked up at the Houten show on June 8 or the Hamm show september 13 this year
regards,
Brenda
