Look into the RM Slayer sxc got a 08 this year with Fox 36 Float's and put a 09 DHX 5 coil on it and it still climbs really good and absolutely hauls on the decent even with my 6' 2" 220lb fat A$$. need to lose some weight but the bikes tough enough to handle it.
Really a great bike Also look into the santa cruz heckler another good choice.
i'm in the saame boat as yourself. you can get good deals on old sx trails but as i can get a weighty discount, i'm going for the orange alpine 160 AM. Easy to look after and bombproof - i hate doing anything other than clean a bike.
I've got the intense ss(straight post version) with a fox talas 180mm and mate it rips! On the downhills its like a mini DH bike, then switch talas to 140mm and I can climb on it.
Only problem is that its heavy, I got mine built heavy at about 17kg. Great work out though if your legs and lungs can carry you
