Hi, I'm not sure what your $ is. You may already have a bathroom scale in the house. You can use that ( with care). Just use a tillering stick, Place one end of the stick on the center of the scale. Place the nocking point of the bow string in a notch at the other end of the stick. Mark your draw length on the stick and carefully pull the bow down to the mark. Read your scale and then relax. Someone posted a link to an ebay seller that had electronic scales appropriate for attachment to a tillering tree. I didn't save the link, but it should be archived here (PA) site, so you might search the old links for "scale", etc. The spring loaded scale from 3 Rivers is nice and simple to use, but I suspect you've already priced that.
