Cheap Power Supplies

[dan3460]

Working on a project and coming to a conundrum. I have design a simple power supply with a power transformer to get about 8V a full wave bridge rectifier and a 5V regulator. I'm costing the transformer and the other few pieces at about $10-11 range. Then looking in the web I came across the following: http://static6.arrow.com/aropdfconversion/a1acc95a5af12e5e2811bf89f539bb2a36261c05/rs-15-spec.pdf?authToken=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJTZXNzaW9uSWQiOiIzZWxlZzFnbGhicGF6eW4xbmZlZmgzMWsiLCJEb3dubG9hZFR5cGUiOiJEYXRhc2hlZXRzIiwiaXNzIjoic2VsZiIsImF1ZCI6Imh0dHA6Ly9kYXRhc2hlZXRhdXRoLmFycm93LmNvbSIsImV4cCI6MTQ4NjA0NzQwOSwibmJmIjoxNDg2MDQ3Mjg5fQ.Da_0wQiCmgh55cdgxR7APFOfTw7m2mQFF6_1-Xiqk_c for about $7, including freight I'm probably are at the same cost as my design.
For my project I need 5V at about 500mA so this unit will have plenty. One of the things that I like from this unit is that will free some space on my board.
Has anyone have any experiences with this type of power supplies?

just buy some cheap USB chargers.

Or something like this:

A little more background on this thing. I'm bringing AC power to the unit and tapping that to power the unit. I don't want it to look cheese, with a wall wart, or a usb tucked inside the box.

These are hard to beat on price and size:

Yes, saw this one but i'm worried that is too closed to the capacity that I need. I'm buying a couple of this to put on the prototype and test. Do you have any experience with this?
