Buyer's regret over Domino XL (DF 700)?

[Clark Hussey]

I bought the 700, and it’s really great for Big Things, when I don’t feel like doing timber framing M&T. But I kept the 500, because IMO the 700 is just plain unwieldy for routine smaller joinery. The 700 is mammoth in comparison to the 500.

This has been my thinking. I feel that if I sell it I will regret it.
