That is actually a pretty cool saw. Never saw it before. I guess the reason for no miter slot is that it has a built in sliding fixture. If the saw works for you, then I assume I would let it be. I was fortunate that I never had to buy my tools out of pocket, I always bought them out of my business. That said, I always let the work determine what tools I need, not the other way around. If you read enough woodworking magazines they will convince you that you can't make a simple box without a $10k workshop. Most of my fixtures and accessories are shop made. Some my design, some I copied. If I felt a regular need for a specific piece of equipment, then I would purchase it. If I could do it another way and still have good results and be time and quality efficient, then I would not buy it. It is very easy to get caught up in the attraction of new tools.
