I have been burning two seasons so far with mine that I bought used.(its 22 years old at this point!) I have broken two grates in two seasons. When I found out how much it was to buy new ones I was appalled at the price! I don't know if you weld or know any one that does but for $35 in one inch solid square bar you can make your own. I just went down to my local steel supplier and picked up I think 10 feet which is a just a little more than you will need. I just took the measurements from the cast grates, cut up the bar and welded it up with my little 120 Hobart. They hold up much better than the cast does.
