Well so I ended selecting to build one after all.
My setup couldn't be easier thus far.
Heavy duty music stand: Ravel Premium Music Stand from Walmart - 30.99

I thought I'd have to build some sort of contraption to extend the face of the board out thinking I wouldn't be able to tilt the face forward enough for topspin. Not the case. This thing leans forward plenty. No mods needed.
So I'll leave the music stand's plate as is. There's holes on the side perfect for simply putting a screw through with a nut on the opposite side for my board.
I contacted a local supplier who had defect uncut rubbers that just fell out of the realm of normal so he can't sell them on his site. Got 10 rubbers for an insane deal.
Now I just need about a 20 by 20 inch board. Thinking possibly MDF in 1/2 thick. That should be plenty strong I would think and is pretty affordable. Any opinions there? Or for sure go a hardwood. Pricier but maybe there's a reason why I shouldn't go MDF? Perhaps the MDF would absorb the glue too much possibly? Hmm...
I'll post pictures & video when the project is fully done.
All in all I'm guessing that this project will cost me.... 70 ish bucks??
For the record, I think that price is outside of the normal given what I paid for rubbers & shipping.
