Peter I have one of those and an SCT. I never use it, even though it works a treat. Use a barlow instead, you will never be able to use the magnification it produces. Infact the only part of it I use regularly is the barrel and the male T thread.
If however you want want place an Advert, I'm sure someone here will have one real cheap.
Sorry you can't have mine as i using the 1.25" /T thread
