Should I Really Buy An Iphone 5?

I have an iPod touch I use for exting and callign and for my music. its perfect.
But I have been saving up from my job and I want to treat myself. I found a good condition iPhone 5 for $430. ITs locked to Telus.
I don’t know what to do. Should I spend that money to get a phone?
On the cheap side though, I have an older samsung phone I can activate if I needed the mobile abilities. Its just I’m not sure if I want to spend that kind of money or if its worth it.
Somebody please give me some advice. Thanks
