As others have recommended, going cheap at first can make financial sense until you get the hang of things.
I found my Arcus 98DAC to be an "awkward fit" when it came to holsters and pouches. I finally found that a Blade-Tech injection molded holster designed for a full sized 1911 worked better than anything else I tried.
If using factory mag's or Mec-Gar's you may do alright with Kydex pouches. I found with the KRD mag's, I had to go leather because I couldn't find a Kydex pouch that fit well. I'm using a Hunter Leather pouch for double stack mag's. I'm not saying that suitable Kydex pouches don't exist for KRD mag's. I'm saying I haven't found one yet.
Good luck, and as others have encouraged, find a way to get out there...you can sort out your gear over time. My first match I used stuff I wouldn't take back ever again, but I'm glad I went out there anyway. At the same time, once you dO "get the bug", try not to skimp too much on your gear. After all, it is a competition and you want to give yourself every opportunity to succeed. At the matches, you'll find a wide variety of gear in use and most I encountered were more than happy to talk about there gear and offer good advice.
Safe shooting,
