If you do like the 1911's then consider moving up to a better platform and just keep your RIA as your backup.
for starters that is funny, i don't think the guys that own 8 RIA 1911's are "starters", or the fellows that have been shooting 1911's thier whole life who own kimber, sa, les baer, s&w and RIA pistols, these people can be found all over the 1911 forums. www.1911forum.com in particular, and www.m1911.org check em out there are alot of happy owners, and if they run they run, that is all the re is too it.A Rock Island is what it is, a fairly reliable $400 1911, and probably not a bad gun for starters.
if a $1000 gun is 100% reliable, and a $400 gun is 100% reliable, seems to me that they are on pretty even playing fields right off the get go.
