Hi all - I'm new to the sport. A few friends have gotten me interested in mountain biking, specifically XC. Looking at bikes now and feel that I would like a hardtail with a max to spend of about $1000. I'm considering the Kona Caldera as an option, but have one friend pushing the GT Avalanche 0.5 because of the reviews it has gotten. Can anyone help me with comparing these to? I've ridden a few Konas and liked them (none were a Caldera, however) but no GTs as of yet. Is it worth checking into? Any other suggestions for a biker just starting? Thanks.
