Puffers are awesome, I had two prior to this guy but they were the green spotted from walmart and I was never able to keep one alive longer than 3 months and I felt like I did my research. But this guy is a figure 8, a lot of the pet supermarkets around here just started stocking them, from what I've read they're much hardier than the GSP's and don't require as much care (smaller tank, lower salinity, greater tolerance, less aggressive) so I picked one up and he's doing great.
