Im starting to look for a new mountain bike seeing as my old ones are too small for me or just not fitting for the type of riding I like to do. Im currently riding a Marin Nail trail which just doesn't have the guts for the riding I like and a Norco 250 which doesn't really do anything except jump around. Im looking for a full suspension, all mountain bike for mild to more aggressive trail riding that wont be overkill for just light rides but has the balls for some more intense rides. I would like to see what you guys have to say would be a good bike for this type of riding, any brands to look out for (after reading the story about marin from Che' I don't trust my old knowledge), good sites to check(using mostly pinkbike now), or any know bikes for sale that you have leads on or have for sale yourself. I am very open to buying used because I have in the past and had good luck, and money is not as abundant as i wish. I have quite a bit of extra parts if needed, and I know bikes pretty well, but any information will be appreciated. Just kinda throwing this out there to see what I get.
Thanks
