Yeah, mine has the hold feature and is 55lbs which is great for everything I sell, including computers. I couldn't see getting a scale bigger than this.
Cost, I think my total with shipping was $30.00. You've got to sift through all the scales on eBay and find the right one at the right price, they are there, I know, Mom recently decided to start selling hand-made curtains on ebay, and the bought a scale last week off of ebay for about that price (55lb)
Good luck!
