Do you not hope to play more in future... gigging etc ?
... surely you don't have to justify buying gear ??

... seriously though it can only be a good thing, but I guess that depends how eager you are to play in future. If it is a slight consideration I'd definitely pick up some of your own gear when you can afford it ... recently I've treated myself to better stuff and it's helped with confidence, and I've generally been more keen to pursue further gigs and play with various groups. Secondhand stuff could be a way to go...
I do hate it though when folk say I'm not good enough for such a nice instrument or whatever... that bugs me a little... this isn't a reference to you btw... just a brain fart.

... so I'll shut up now...
