You should be able to find several very nice Glasco or Ideal Sliders for under 900.00 !!!
for my nice original Glascos, with rack, coin mech and rewired for safety, I have been getting 650-700 for those...
Let us know where you are located and I'm sure there is a member who has or can find you a slider within your budget.
I have several available as well, and I'm in Northern Wisconsin.
