Opinions please for buying a bike

I am fairly awkward when I am buying a bike. My one that I have been using has passed it's day and I am looking for something more robust and to my geometry. 
What I am looking for is a strong hardtail with preferably less gears (1,8 or 9) and I'm not fussy about the weight at all (17kg/37lbs or less). My riding style is quite rough but can make mistakes quite often (such as entering corners too fast) when I do a range of trail riding/XC with sometimes dirt-jump included.
To know my dimensions, I am:
Height: 71.5" (182cm)
Inside leg: 35" (89cm)
Arms span: 74.5" (189cm) (Yes I am a bit like a monkey)
I have been looking at the NS bikes Core 2 for example but it is slightly out of my pricing range but the Core 3 had bad reviews so I am avoiding that. (Please keep the price on the low end.) :roll:
Can anyone suggest anything for me? Thanks

My god road cycling is scary! I'm going to keep my relaxing rides to the trails where everything is green, fast and less crazy.

Might be worth looking for a used Charge Blender, On-One Summer Season or NS Surge.
EDIT - like this one perhaps? http://www.ebay.co.uk/itm/Cove-Stiffee-Fr-complete-custom-build-/140875530716?pt=UK_Bikes_GL&hash=item20ccd601dc (not mine)
