avoid any like this

or any using Omega rims/parts.
There are 2 main type of cheap hubs, Quando and Formula. Quando ones don't have sealed bearings, are made of a shit metal and are generally awful. Formula's cost a little more but have sealed bearings and are generally great.
Quando's look like this
http://d3d71ba2asa5oz.cloudfront.net/62000107/images/rgh957n7.jpg. They come on Create/Espresso/any other no name brand wheels, usually with a deep rim which is equally shit. Avoid them all together.
Formula's look like this
http://www.bellsbike.com/Pix%20by%20SKU/466_black-rear-fix-fix_large.jpg and are rebranded as things like Planet X, Ambrosio, Origin8, Velocity, Joytech, System X
The easiest way to usually tell between Quando and Formula is by the cut outs on the flanges.
I would also say avoid Miche, they use an Italian threaded lock ring and also use a shit metal. In fact avoid anything made my Miche.
Then there are other makes like Halo, Goldtech and more expensive ones like Dura Ace, Suntour, Phil, Royce etc.

A decent and relatively cheap set of track wheels would be something like these Navigator Street Track wheels

They are pretty much the same as all the other wheels around the same price. Whether they're branded as Ambrosio or whatever, just like this http://www.actionbikes.co.uk/ambrosio-pista-track-wheels-pair.html

That said, you may be able to pick up a good second hand pair of wheels off here for about half the price. If they have Formula/Joytech/etc hubs and are a bit old you can just buy new bearings for a few quid and pop them in as they're sealed.
