Regular front road wheel for a single speed bike
There's no such thing as a 'single speed specific front wheel'. I think what you mean is you are looking for a front wheel with a threaded axle that is fixed in the fork with nuts, rather than a quick release. Such wheels are used on inexpensive department-store type bikes as well as quality single speed or fixed gear machines.

My guess is that you are finding replacement wheels aimed at the former type of bike which will will indeed be cheap and heavy. As Andrew Henle said in a comment look for track wheels. Also look for SS/fixie specific online stores.

Update:

You may have a problem with a quick release hub wheel as (I believe) threaded axles are 10mm diameter whereas front QR axles are 9mm and will move in the 10mm wide dropouts. 

Front threaded axles are SAE 3/8" x 24tpi which is 9.6mm outside diameter.
