An SBR is more than worth it. I have a lot of time on 8", 9", 12", and 14" rifles and shotguns. There is a huge improvement in handling in confined areas compared to a 16" rifle or 18" shotgun. Besides, an extra $200 is nothing compared to the cost of the rifle, mags, optics, sling, and everything else. Once you're into it $2000+, the $200 to get the barrel length you want is insignificant.
