Valve seat cutting

I have grown tired of hauling my heads back and forth to the machine shop to have valve seat work done, and I'm ready to invest in my own equipment.

My intentions are to tool up to be able to do competition quality 5 angle valve jobs at home. With that being said, I have been looking at both Neway and Sioux products. I understand that these are not the most time effective ways to do valve jobs, but this is just a hobby and time is not a factor.

I know that the Sioux stone systems are still very popular, but do they have advantages/disadvantages vs the Neway?

What do you guys have? I'm getting quotes on flow benches at the moment, so I don't think that a sunnen or rottler is something that I could pursue and continue to be married. Also they would not really be practical for what I will be using them for anyway.

Thanks in advance!

You can do what you want with either, with stones you can try different things real quick, remember this is how it was done for a long time with good results. New machine/cutter machines will always be more accurate but you can still get very good results with stones at home

I have a really old Thor seat and valve grinder. I have done many heads with them and still does a great job.

Thank you fellas. Yes I didn't really think about the benefit of the quick try/experiment element with using stones, so I am leaning that way.

I would LOVE to have a Thor or one of the vintage Sioux grinders or facers. I do see them on craigslist from time to time, but those folks usually know what they have and what they are worth.
