Oh man, that's a tough call.
Before you decide, let it cool down overnight. Unplug it, turn it on, then off. It is possible that once all the capacitors are discharged, it may fire back up. Summer heat may have caused the shutdown. That thing is pretty cool. Definitely worth keeping, but that's just my opinion.
On the other hand, you might spend a day or two looking at Facebook marketplace. That's where I found two really nice sets over the last couple of months.
Good luck. Start another thread if you feel like it. I'd like to see how this turns out.
