Welcome to RG! There's a lot of Seiko love on the forum. I have 2 myself, an SRP309, Orange Monster and a SNZH57J modded to a FFF. Plez post pics when you can.

IMO, getting a rep before a gen is a good idea. You get to see how much you love it before spending a great sum on the gen. There are some good repped Omega SM and some not so good. Read the reviews for both the SM and TDs
