What's the ideal PSU for a dreamcast right now?

[Lila Corpsegrave]

I'm worried that my PSU might be dying, or something of the sort. Or, at the very least, I get overheat issues during the summer months, and I've been putting off upgrading it for too long. I've done bits of research here and there over the past couple of years, but I keep finding conflicting opinions from the different people I've asked. I'm hoping to come to a final decision, but I want to make sure I'm picking the best option because my Dreamcast is my baby. What are the various alternate PSUs I could install in my DC, and what are the pros and cons of each?

I can't tell if it's the best option but I would recommend the dreamPSU. The design is Open Source, buying from a chinese manufacturer is legit.
