I really think ading the 200 model to your lineup would be a great addition. The quality level is a few notches higher than the model 74.
The 800, also is a much higher quality model, and is stainless, but not everybody is a stainless fan.... The price on that one is also significantly higher.
Here's a shot of a set of three random GDs to show what Ken is describing with the heels. The one on the bottom doesn't look too bad, the top one has a bit of heel overshoot, and the middle one has a bit of a wavy edge.

Nothing that is un-fixable with some time and effort. But certainly don't think you will necessarily just be able to hone them up and go (on some of them you can, on some, it takes a fair bit of work).
And of course, I I can attest to, if you do like to mess around with them, they are perfect for doing so!:)
