Best options in the US are:
1) 12" Silent Runner - this is actually silent - has ball bearings, spins really well and has a safe sturdy stand. It's 35cm tall on its stand. I have this wheel and it's great for a Syrian.

2) 11" Wodent wheel - silent runner is better
Wodent wheel is more space saving but fiddly to keep stable sometimes.

3) 10" Carolina Storm Wheel - height adjustable and sturdy - only really for small to average sized Syrians. Quite deep and bulky in a cage.
