Without a doubt, buy second hand.
Take a look on ebay around the £500 pound mark for something including cymbals.
Look for Pearl, Tama, Premier, Yamaha, Mapex, Sonor, Gretsch, PDP, or ddrum.
And for cymbals, Zildjian, Sabian, Meinl, Paiste, or believe it or not; Stagg.
Something like this would be perfect: [url="http://www.ebay.co.uk/itm/Sonor-503-Series-Drum-Kit-/251163814324?pt=UK_Musical_Instruments_Drums_Percussions_MJ&hash=item3a7a87a9b4"]http://www.ebay.co.u...=item3a7a87a9b4[/url]
or this: http://www.ebay.co.uk/itm/Premier-Drum-Set-Sabian-Cymbals-Muffling-Pads-and-8-Drum-Sticks-/150913740984?pt=UK_Musical_Instruments_Drums_Percussions_MJ&hash=item232328f0b8
Look at those, top level drum manufacturer, not just some cheapo brand (CB or similiar), and you get a set of named cymbals! All for a very agreeable price!
On which note, all of the major cymbal manufacturers make budget ranges. However they're made to be budget and as such they will intentionally make them to not be as good as their professional ranges. Stagg cymbals come in at the same price as the big label budget ranges, but they're made to proper levels. The long and short of it, is that if you're wanting cheap cymbals, go Stagg (Ideally their DH range), rather than getting a budget zildjian or sabian set.
