I think for a lot of musicians it comes down to want or need. If you need it and can afford it you get it. If you just want it then you have to decide. I'm a practical person and with the business end of music slowing down for me I'm not buying anything new. Moving a few times over the last few years has also got me on the less is more path. Got rid of a lot of things I just liked having around but really didn't need. I do miss my B3, Studio Piano and motorcycle but times change.
I do have a small mixer for my DJ setup on back order from Sweetwater. BTW its a Behringer mixer and all their stuff is on backorder beause their gigantic factory in China got hit with an earthquake.
The new JBL Eon One PA and a few keyboards have me tempted but I'm staying put for awhile. I'm getting more into just playing piano on my Casio Privia and by that I mean more attention to music and not the programming, etc. that goes along with my BK9 arranger.
