What's your budget? I would recommend a 2021 CG-125 tank, as they look good and are in great condition, for cheap. I "think" they may fit onto the deluxe. Most likely yes, but don't quote me on that though. They go for around 8k.
If that is outside your budget, look what I found for a mere 1,000. It's also a 125 tank.
Last, but not least, you can repair the tank, to make it work for a few months, but you will be back at square one again soon. Not a permanent solution.
