My habits have changed over the past couple of years, too. Originally it was "1) this is a gun, 2) I can afford it, 3) Mine!" Hard times forced me to sell off everything except the one heirloom .22 I had and a Sig P6.
Now it's 1) Save for a year+, 2) Buy/build exactly what I want, 3) Have an accurate, reliable weapon that I don't ever want to get rid of. Life was also made a lot easier when I made myself the rule of only .22, 9mm, .45, .223/5.56, and .308. Actually, been thinking about further consolidation including phasing out .45 and/or standardizing on certain platforms (Glock, AR).
