I've used Meanwell before they make quality supplies for a reasonable price.

If you stick with the known brands you'll be ok just stay away from the dirt cheap no names they will likely have crap caps and no EMI filtering.

I've just repaired one of these PSUs, the output was at 2.7v. Replaced C3 10uF 50v (the little one just above the 8pin controller chip A6351). Now output is back to 3.3v. The electro didn't look bad but did not register on my ESR meter.
