Hmm - not so much machine lust, but the desire to buy another machine exactly like the one I currently have and really like. I have this thought that I better have a spare stowed away because someday my current machine will give out and I won't be able to find another that I like as much. Kind of like buying several of the same shirt or pants because they'll never make anything like those again in my lifetime! Argh - why do I have anxiety attacks over stuff like this??!!
