On the price, it's the same as the Turbo CD solution they sell, the SSD3. In both cases, you're getting (hardwise-wise) a well made product CIB, and you're not having to buy (or keep) your old systems if need be. Good luck finding a Turbo CD add-on working for under 150, or a Sega CD under 90-100.

Krikzz at this point is simply "updating" based on the availability of new chips. For instance, he just announced a new N8 (NES) cart, with a laundry list of new features that 98% of users won't use or notice. These are minor upgrades, albeit at times necessary for him because prior chips go out of print. Terra Onion spent 2.5 years (behind closed doors) developing this product. It's a big time investment of time and effort that I'm not sure Krikzz has at the moment. His upgrades are relatively easy. He increases the power of the device, and that allows for new features he's already tested.
