@Curt Don’t you have a JTP laser already? Are you looking for another one?
As Steve mentioned, the L-cheapo looks okay but the driver is really the key. If I were looking for a second laser module, I’d start with this: http://www.banggood.com/445nm-2_5W-2500mW-Blue-Laser-Module-With-Heatsink-For-DIY-Laser-Cutter-Engraver-p-993521.html. Less than $90 shipped from their US warehouse.
I’m very happy with my JTP laser. It’s a more expensive option, but it comes with everything you need, and works great right out of the box. The laser is controlled using the cooling fan output of the ramps board and M106/M107 commands. Easily generated in inkscape, estlcam, image2gcode, piclaser, laseretch, and other software.
