Wenn sie dir bei Youtube klanglich gefallen hat, ists doch super. Nur dein Geschmack zählt und der Preis ist auch OK.
Ich würde sie an deiner Stelle solange spielen, bis ich klanglich etwas wirklich viel Besseres gefunden hätte - Marke, Material und Preis würde mich da garnicht beeinflußen.
Material wird übrigens NS 12 sein (NickelSilber).
Nickel silver:
Nickel silver as used in cymbal making is an alloy of copper and nickel, and an alloy with about 12% nickel (The usual formulation of Nickelsilver is 60% copper, 20% nickel and 20% zinc) is used for some beginners' cymbals. A very few specialised high-quality cymbals are also made from nickel silver, as are some top-quality gongs tending to the more modern and exotic sounds.
Some maintain that the term nickel silver should only be used for alloys containing an appreciable content of zinc, and would call this cymbal alloy nickel bronze instead, but the use of the term nickel silver for all cymbal bronzes with nickel as the main alloying metal is well established.
Nickel silver is malleable and available as commercial sheet metal, and gives a bright tone but without the shimmer and sensitivity of tin bronzes. In the early to mid 20th century nickel alloy cymbals were far more widely produced and used, and so many older recordings were probably made using cymbals with a significant nickel content.
Evelyn Glennie is particularly noted for exploiting the tones of nickel silver cymbals.
Examples of nickel silver cymbals include: Some Foremost, Meinl Streamer and Marathon N12, Paiste 402 and some Exotic Percussion, Sabian Signature Glennies Garbage, and some Zilco.

Soweit ich gehört habe, waren die ersten Generation X Becken (Thomas Lang) auch aus Nickelsilber, heute heißt das Material FX9 (was immer sich dahinter verbirgt 
)
Other metals:
Cymbals have also been made from silicon and aluminium bronzes but these alloys have not become generally popular.
Meinl FX9 is an alloy of 69% copper, 15% manganese, 15% zinc and 1% aluminium, and was used for the new Meinl Generation X line released in 2003. Previous Generation X models were made from malleable bronze. FX9 is described by Meinl as not being a bronze at all, and was previously described by their sales literature as containing tin rather than zinc. There is a minority view that the word "bronze" should be reserved for two-phase alloys, which may be their usage here.
Unlike cymbals, some gongs are made from several different metals fused together. Many different metals have been used. Parts of some traditional gongs, notably the bosses of some "nipple" gongs, are made from iron based alloys.
