As said there are deals out there to be had that is much much better. I know because I picked up on some of them.
Look around. Have some patience and the right deal may find your way.
Keep in mind that if you find a good roller, you'll still need to get a good motor for it. 1/8th motors will run you upwards from $350 for a good motor. Be careful of "used" motors from owners claiming to have only ran 5 or so tanks or "less than a gallon" as those claims are often never true.
