New to RZRs and UTVs

Just wanted to say hello and introduce myself. Bought a 15 900 S EPS about a month ago and have taken it out several times so far. So far I have got a poly roof and half windshield. I plan on adding lower doors and getting a pre filter very soon. I live in Springfield, MO and wanted to know if there were any members out there who are in this or surrounding towns? Would love to get to know some other folks! Going to be doing the first service in a few days. Any suggestions on getting a better price on a replacement air filter and oil/filter than going to a dealer?

Look forward to learning and getting to know you all!
