The KDTV DVDS are on sale for $20! I see ALL Series, 100 thru 900!!! The disc SETS, not just video downloads. I've never seen them so deeply discounted. That's half price! $180 for Series 100-900 is less than you'd pay for a full day class at Stitches, which is about $240! Half day classes can run $120! And they are a one-time shot! If you don't really GET IT in the six hours, or 3 hours, you are screwed. You got nothing but a great social gathering.
I prefer owning the DISC SETS. I can play them anywhere I go on vacation in my Sony DVD player, sometimes right here in my TV room when my hubby is monopolizing the TV! I knit along as I watch, and sometimes I have to 'study' what she's teaching!
