First, you need to buy the bike online or at bike shop? Not every brand available in your area bike shop. So if introduce the brand that you are hard to find in your area what you gonna do?

This one may be fall in your budget. But I not sure you are aiming hard tail or soft tail.

With that budget can look into Polygon brand. Polygon is very well established and global brand. Made in Indonesia.
Java, Camp, Comp, Alcott, Twitter all made in China and not a reputable brand.

Your budget fall into Giant Talon. I not sure is either model 3 or model 2 but the price seem very close.

For those riding MTB final destination sure will go for full suspension. Since you already ride so many years of hard tail and willing to spend more on this sport why not give a try on soft tail?

My first time heard about the XDS brand in Malaysia around 2009 ~ 2010. Got people bring in their bike selling in here. Rm7xx~Rm9xx already got full alloy hard tail. Rm12xx already got alloy full suspension model.

Until today this brand still survive because quantity they selling out are huge in china. Some more they majority do OEM business. Some of their model just paste the XDS sticker but exactly same like those famous brand one.

Wonder why you want to purposely seek for this brand?

recently I just notice RM5k can let you get a entry setting DH bike. LOL

If get a reputable brand, no worries on the "old story" about full suspension bike bouncy, etc.

I just go to see the detail of the spec. If really serious then don't buy D5. Minimum need go to D6.
