Hi Riaan,
This has been on my want to do list for a couple of years now. I my price range is the $1,000 mark but still after reading lots of reviews haven't decided on one to buy yet.
I have been considering this one ROBO 3D R1. I'm not sure how the ABS or PLA material will hold up to the stress's.
Drone Rotor magazine had a article this month on a few different materials, such an nylon but it requires a metal hot end due to the higher temps needed for the nylon.
supposed to be a follow up article next month with carbon fiber material.
Good Luck.
Gary
