Weld that thing it'll work a long time. Have a bead put in it with no contamination or porosity/bubbles crappy bead, a little V grind very tenderly done before welding so you get a deep Bead. Dremel fine stone for that. At least it's not plastic crap. Metal is at least fixable in this area from your discription. Don't buy a new one for Christ's sake just repair it and save $1500 bucks or whatever those run.
