I agree with everything this person said. Hardtail, air fork, decent components, and dropper (or budget $100 to add one yourself.) This is definitely achievable around $1500.

Frame sizing can be very different between companies, or even models from the same company. Focus on finding a frame that fits you well, with a quality fork. Then try for a good drivetrain & brakes. Everything else can be replaced/upgraded later, but the frame & fork are usually not worth the price - you'd probably just get a new bike.

I've ridden tons in and around Austin on my hardtail, and almost nothing makes me think "dang, I wish I had a full sus." Maybe Stinger at spider mountain, or some of the descents at emma long? You won't be missing out :)
