Help with specs for deciding which Benq projector

[Alcoholica]

Hi everyone! First post here, but I've been reading a lot!

I'm building my garage sim and need your help with a projector.
Screen is floor-to-ceiling 113" and 107" wide. I know I'll be showing a 4:3 image and don't expect to fill the screen height wise, but would like to fill it as much as I can.

I was planning on having the hitting area around 8ft from the screen. I have some flexibility there. (Planning on the Garmin r10 launch monitor, which will be another 8ft or so behind the hitting area)

I know a lot of people use the th671st projector, but it's a bit out of my price range. Need to be under $500, and was really hoping to find something in the $3-350 range.

I don't have a computer to hook up to the projector, so I was going to try and use my phone. If I had to, I could get a cheap android tablet to use. I know nothing about those though. (I don't own a tablet)

I know Benq makes a good quality product. I was looking and reading about the MW632st, which according to Projector Central, would fit the bill. There are so many different projectors, I've confused myself! The only downside I've read about regarding the 632 is the resolution. Of course I want a clear image, but I need to stay in budget.

I am most likely going to be in the used market to keep cost down, unless I find a killer deal on something.

Any thoughts and recommendations?
Thanks everyone!

Oh, should have mentioned this is a ceiling mount application and I do have room to offset mount it or put the projector right over me. I know my club wouldn't hit it, but it still scares me. I was leaning towards mounting it off-center for peace of mind, but don't know which projectors would have corrections to be mounted that way.

Is it better to have WXGA ratio and change it to 4:3 or to have a native 4:3 xga?

One on my list is the mx819st, that is native 4:3 xga, but it's a .61 throw, and I would need to mount it closer to the screen. I'm hesitant of having the projector that far in front of me.

All the other ones are WXGA and don't know what would be better.

I pulled the trigger on the me632st. It was less than half the cost of the 672, so we'll see how it works out.
