It looks like Intech has brought their software sales in-house after working with OWC... that's kinda weird:

https://www.speedtools2.com/shop.html

They want 59.99 for Hark Disk Speedtools, by itself! That's criminal for a product that hasn't been updated in 12 years.

At least at OWC they'd give you both HD Speedtools and CD/DVD Speedtools for that price!
