I am a huge lover of the Python, mine has made my cmdr the rich guy he is today and will always fight it's corner BUT I would not sell my other ships to get one. I saved up doing passenger missions with my AspX, saved until I had about 200mil in the bank so I had enough to buy, outfit and have plenty of rebuys. Within days I had that 200mil (and more) back thanks to the Python.
I have only ever sold 2 of my ships, the T6 I had to get the money to buy my AspX (I hated the T6!) and an FDL I bought once I reached Elite in trade and had access to Jameson, I got giddy and bought and A rated it, flew around for about 30 mins, realised it didn't suit me or my play style and sold it again.
I still have my Sidey, Cobra MKIII, AspX, Python etc.
