Was considerably less than that when I got mine. Afaik they are being phased out by TV but might still be available from some dealers. For high powers (where barlowed eye relief is fine) a plain old well made 2-element barlow is preferable so I like the option of being able to remove the extra two elements that correct for eye relief. On the downside, the interface+barlow is a bulkier package and there is more glass to protect from dust etc.
