I did exactly this on the table in my parents house. It was a standard, run of the mill Sportcraft cheapo. I was home from college when I did it. The corner ramps will come out easily. The goalie rods have places on there for the two other men - taken up by the pieces that limit the rod travel for just one man. I removed all the rods and cleaned the existing bearings (plastic guides that the rods slide through). This made a HUGE difference. While the rods were out, I buffed the playing surface with some 220 sandpaper and then medium steel wool to smooth it out. That gives the surface a dull finish kind of like the Tornado's, which greatly improves controllability of the ball. I then cleaned everything up, put all the Tornado men on (I used the non-counter balanced men to save a little money) using their roll pins (worked perfectly), and lubed the cleaned rods with silicone. Believe it or not, that table plays REALLY well for a cheap table. Of course there's nothing like a Tornado (unless the Ricochet table I bought turns out to be solid - haven't set it up yet), but for what this was, it worked great. And it should go without saying that you need to switch to a polyurethane ball if you haven't already. (and if you haven't...seriously - what's up?)
I've never heard of the Carrom men, but if they look just the same, I'm sure they'll work.
Fixing up a cheap table with Tornado men and cleaning up the bearings and playing surface is a viable option for someone on a tight budget who wants a decent home table. Also make sure you tighten all nuts, bolts, and screws that hold the table together.
