You'll need to be more specific... I did a search of their inventory using the search terms "reinforced spur gear" and got no results (even using the correct spelling). If you mean a steel spur gear, they range from 17 bucks up to around 30 - but again you'll need to be more specific if you're after an accurate answer.
Go in and talk to Chuck, he knows his stuff! He's helped me alot.
