Which bike should i get?

Hello I'm 14 and I'm pretty good at BMX biking I can do feebles, ice piks, tooth piks, 180's, almost 360's but I'm kinda poor and so I can't get a wethepeople bike or something like that *to exspensive* but currently I have a Sims bike and I wanted to get a second bike because my sims one breaks everyonece and while so while its being repaired I wanted to have another bike so should I have 2 sims or a diamondback? Thanks
