A friend of mine has just launched a new hardware product for the sim racing scene, it's seriously cool and a very reasonable price.
It's a completely custom designed and built product, he has just started selling the first production batch. Be quick if you want to secure one.
Check it out here:
http://siminstruments.com/He has said he will accept any orders paying with Bitcoin, so either send an email with your order details to their contact email address, or just let them know you want to see a Bitcoin checkout option on the website. Maybe if there's enough interest they'll add it.
There's a good review here:
