I have a nearly new megablaster2 for sale, it has 2 motors, you can use either motor on its own or both together.
It is very powerful and is meant for large or giant breeds.
Cost £425.00 new last year would like £200.00
I live in somerset.
Are there any shows which you are due to attend, apart from Crufts in which you could bring it with you so i could have a look. I have been toying with which blaster i want and this sounds ideal for me.
Somerset is a way from Sussex, but i am prepared to meet half way somewhere, though would need to try it on my dog somewhere to make sure i am happy with it.
PM me with your details and i can contact you.
