Yeah James. I'm working on getting some more protective gear.
Since I already have a plate in my neck I'd love to have a Leatt brace and they are expensive but being seriously injured or worse is not something you can put a price on. All I have so far are a helmet and a pair of ladies Thor boots but I'm going to have to extend or raise the gear shifter to wear them so I wear work boots right now. No tennis shoes for sure! Thanks for the warm welcome from you and the gang!

Ouch, I'm guessing that isn't from bikes though? Yes you're right a neck brace that costs $400-600 is a very small price to pay, especially when you have the misfortune of actually using it for its intended purpose. I currently wear the Leatt but I've heard that the Alphinestars one isn't as restrictive, might serve you better for trail riding.
Besides the 2 givens (Helmet & boots), you might also want to check into knee pads (or braces if your budget allows), chest protector, and some MX pants as they'll over more protection then jeans. And of course the neck brace.
If you need help with adjusting the shifter just create a thread and we'll help you out.
