I've got $500 to blow, Sumo or PMMM?

I bet this has been beat to death and I apologize to add yet another thread to this topic but I really appreciate anyone who's willing to give me some advice.
I did do a search and spent a lot of time in some of the other threads and haven't seen this exact topic covered. Please direct me if it has!

I love the look of the MM300. I will never be able to afford a MM300. I have $500 to spend. So I'm looking at either getting an SKX that's been modded, or the Sumo. These are the two watches I feel will give me the most MM300 vibe on a budget, I've looked at the Tunas and that case shape is not for me, sorry. I love the Sumo's dial and I'm blown away that such a great dial could be had at that price, however the bezel, flat case shape and long lug size looks like it might be a turn off for me, but I can't know for sure because no dealer by me carries it, and it's impossible to get a sense of how it really looks on an arm because all the pics of it online are taken 4 inches away from the dial. (My wrist is 7.5" so I think I could pull it off, but just aesthetic wise it might be too much watch for my taste).

Whereas I love the case and shape of the SKX007, but not so much the dial. So a PMMM seems like the right choice, except with a PMMM I'm subject to the expertise of whoever did the mods which could've been done poorly and I'm likely going to lose the WR, am I right in assuming that?

So my questions are:
1. Are PMMMs I find on ebay and other places a safe bet or are there sketchy mods out there?
2. Is there a place online that sells professionally constructed PMMMs?
3. Does an SKX171 that's been modded lose it's 200m water resistance?
4. Can any Sumo owners here post pics of themselves with their Sumo's, but panned back a bit to see how it looks in relationship to a full arm/torso/body? My kingdom for a video of someone standing 20 feet away from the camera wearing a Sumo and just rotating around.

Appreciate the help!
