Jaked, if you really like the bike, well, even at that...If you really want your bike to be 100%, just get it. Soon you'll forget how much it cost and you'll still be riding on an amazing shock.
I recommend getting the brand thats popular your country. Here in the usa, penske is very popular and we have all kinds of service centers to choose from. If hyperpro is popular where your at, than by all means do that.
One nice feature to have is adjustable shock length. Spend enough to get that. By that level, preload, compression and rebound will be there, too.
The length adjust is very nice because it allows you to set the spring tension perfectly, AND have independent control over rear ride height.
