Any suggestions on a good stem?

Hi Guys,
Im looking to change my setup from a long reach stem bullhorn to a shorter reach and flat or potentially riser bars.
Its an SE lager with 1 1/8" threadless

Have been looking at thomson elite BMX 25.4mm clamp size, they seem pretty high quality and with a short reach on them.

Is there any bike stores in sydney that have a good selection of stems ?
