The PPS M2 is excellent. Great trigger, and in my view the best ergonomics of any gun in its class. Plus, and unlike Glock, Walther gives you 6, 7 & 8 round factor mag options. Another upside is the pin on the back of the striker plate that gives you tactile feedback to prevent a negligent discharge on reholstering. Awesome gun all the way around. $299 is a solid price. Consider also in the budget genre the S&W SD9VE and Taurus G2/G3, though two of those are larger than the PPS M2.
I've had 3 of them, the original with the euro mag release was the best. I sold all 3 to new shooters who loved it when they fired it. One of the BEST compact 9 mm's.
It's $314 with shipping, I wonder if Buds would match the price...(Hmmm, maybe I NEED another one)
I am back carrying the PPS, and am very happy with it. I chased novelty capacity and went 360 degrees back where I started. It shoots very well, I actually practiced with it today and once again it it performed flawlessly.
