The cheaper aftermarket cranks need to be carefully checked for dimensions and tolerances before engine assembly. The nose of the crank is one area where I've seen problems before.
If the crank nose is smaller than spec then you'll have find a damper that is also undersize. Most of the aftermarket dampers are made slightly undersize so you have to hone to fit so you might get lucky and find one that fits.
Time to invest in a set of good micrometers.

If it justs " pushes on", and doesnt have to be DRAWN ON, its not right. Like CAB says, the balancer needs to have a press ( interference fit) to work correctly. Otherwwise, its doing nothing but CREATING harmonics, exactly what it not supposed to do. Get a balancer that fits right, or have someone that is experienced give you a better look at it. Sometimkes, like Andy says, the snouts can be too small, but a decent balancer will usually have room to hone it out for proper interference fit. The only way to properly hone a damper is on a rod hone by the way.

I was looking online and found a place called Speedmaster. They have a nice fluid one for $200 part #PCE291.1067. But I am still trying to find out if it will take stock pulleys. I didn't want to spend more $. But you guys are rite. I have too much already invested to be cheap now.
Don't get a fluid filled dampner. Good aftermarket balancers will be undersized and must be fitted to the crank snout.
I got a Pro Race pro sport thru Mancini , it's MP Hemi Race balancer , I haven't installed it yet but it is supposed to use stock pulleys.

The harmonic balancer isnt an area to go cheap... I use only ATI on all builds except resto stuff..Very high quality and the hubs are always either dead on or too small, which is simple as a quick hone to get the proper fit... And dont use Mickey Mouse tools,(like a block of wood and a hammer-then draw it in with the crank bolt..  )..Get a proper installer with a thrust bearing or borrow one..The nice thing about an ATI is the hub can be installed independently of the ring and I always warm up the hub in my hot tank to make the install easier.. BTW..If using an ATI, Doty(DMI) sells the pulley with the right offset to allow all other stock pulleys to work...Otherwise call Jones Racing Products and get a hub/spacer/pulley..They have the configurations to make it work without much fuss..

For what it's worth, my antivirus program did not like something on that page.
No issue here and the firewalls on my work are very sensitive ???

I would measure the snout and balancer to figure out which one is not correct on which diameter 
Sometimes the "cheap way" will kill you or your parts
